** Description changed: Binary package hint: alacarte "Main Menu" worked with first ubuntu 8.04 installation. After serbian language pack installed program did not working any more and in the terminal generate errors such like this: u...@computer:~$ alacarte Traceback (most recent call last): File "/usr/bin/alacarte", line 36, in <module> main() File "/usr/bin/alacarte", line 32, in main app = MainWindow(datadir, version, sys.argv) File "/usr/lib/python2.5/site-packages/Alacarte/MainWindow.py", line 49, in __init__ self.editor = MenuEditor() File "/usr/lib/python2.5/site-packages/Alacarte/MenuEditor.py", line 35, in __init__ self.locale = locale.getdefaultlocale()[0] File "/usr/lib/python2.5/locale.py", line 443, in getdefaultlocale return _parse_localename(localename) File "/usr/lib/python2.5/locale.py", line 375, in _parse_localename raise ValueError, 'unknown locale: %s' % localename ValueError: unknown locale: sr_ME Error in sys.excepthook: Traceback (most recent call last): File "/usr/lib/python2.5/site-packages/apport_python_hook.py", line 78, in apport_excepthook report_file = open(pr_filename, 'wt') IOError: [Errno 13] Permission denied: '/var/crash/_usr_bin_alacarte.1000.crash' Original exception was: Traceback (most recent call last): File "/usr/bin/alacarte", line 36, in <module> main() File "/usr/bin/alacarte", line 32, in main app = MainWindow(datadir, version, sys.argv) File "/usr/lib/python2.5/site-packages/Alacarte/MainWindow.py", line 49, in __init__ self.editor = MenuEditor() File "/usr/lib/python2.5/site-packages/Alacarte/MenuEditor.py", line 35, in __init__ self.locale = locale.getdefaultlocale()[0] File "/usr/lib/python2.5/locale.py", line 443, in getdefaultlocale return _parse_localename(localename) File "/usr/lib/python2.5/locale.py", line 375, in _parse_localename raise ValueError, 'unknown locale: %s' % localename ValueError: unknown locale: sr_ME ProblemType: Crash Architecture: i386 Date: Sun Apr 27 23:08:17 2008 DistroRelease: Ubuntu 8.04 ExecutablePath: /usr/bin/alacarte InterpreterPath: /usr/bin/python2.5 Package: alacarte 0.11.5-0ubuntu1 PackageArchitecture: all ProcCmdline: /usr/bin/python -OOt /usr/bin/alacarte ProcEnviron: PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin LANG=sr_ME SHELL=/bin/bash PythonArgs: ['/usr/bin/alacarte'] SourcePackage: alacarte Title: alacarte crashed with ValueError in _parse_localename() Uname: Linux 2.6.24-16-generic i686 UserGroups: ------------------- INFORMATION FOR SRU CONSIDERATION FOLLOWS: 1. A statement explaining the impact of the bug on users and justification for backporting the fix to the stable release: This bug prevents users in some locales (notable Serbia and Antigua, sr_ME and en_AG) from running locale-aware Python software in Ubuntu, including alacarte and software-center. The latter is particularly problematic, as it is likely to affect many novice users. The proposed fix is small, clear, in the upstream bugtracker already, - and is isolated to one file, and has been used with success by users of - Ubuntu Karmic in both the mentioned locales from a PPA. + and is isolated to one function in one file, and has been used with + success by users of Ubuntu Karmic in both the mentioned locales from a + PPA. This appears to qualify as a bug ... "which represents a severe regression from the previous release of Ubuntu. This includes packages which are totally unusable, like being uninstallable or crashing on startup." It could perhaps be argued that these locales did not exist in earlier versions so this is not technically a regression? 2. An explanation of how the bug has been addressed in the development branch, including the relevant version numbers of packages modified in order to implement the fix. An attached debdiff for Ubuntu Lucid is attached to this bug report. It awaits sponsorship. 3. A minimal patch applicable to the stable version of the package. See attached debdiffs. The original patch is at http://bugs.python.org/file14881/locale.py-parselocale-patch.diff 4. Detailed instructions how to reproduce the bug. TEST CASE: 4.1 Install Ubuntu 9.10 Karmic Desktop (i386 and amd64 have both been tested). 4.2 At the GDM login screen, set the locale to English/Antigua and log in (start a session) in that locale. 4.3 Click on Applications -> Ubuntu Software Center 4.4 To see the Python traceback, open a Terminal window and run software-center from it. 4.5 If desired, obtain the patched python2.6 package(s) from the PPA at https://launchpad.net/~jmarsden/+archive/ppa/ and repeat the tests. software-center will now run and operate correctly. 5. A discussion of the regression potential of the patch and how users could get inadvertently affected. - Not every Python app has been tested with this patch, nor has itt been + Not every Python app has been tested with this patch, nor has it been tested with every possible supported locale setting! So, by definition, there is a non-zero regression potential. Nevertheless, the patch is so small, and can be reviewed by anyone who reads Python for correctness. It affects just one function, and then only in locales without a period in them (there are few such locales). On that basis, it is hard to see how it can really introduce a regression in practice. This issue has been around for several versions of Ubuntu, so the current behaviour with the patch in place (for locale-aware Python applications at least) is an obvious improvement over earlier behaviour -- the applications actually run. So far, no Python apps have been found which this patch affects negatively. The patch has been tested in several commonly used locales, including en_US.UTF-8, de_DE.utf8, es_ES.utf8 and fr_FR.utf8, as well as the affected locales sr_ME and en_AG. -------------------
