Public bug reported: It began to fail after updating to Ubuntu 18.04. This reproduces the bug on my side:
1) Edit p1.cc with the following text: "hello, world" (no quotes) 2) Edit p2.cc with the following text: "hello,world" (no quotes) 3) Meld them 4) Correct p2.cc with p1.cc's contents. 5) Control+W to close tab, it appears the "Save" dialog, save the changes I expected the tab to be closed after saving, as usual, but the tab was not closed, and cannot be closed afterwards neither with Control+W nor closing the tab with the mouse. On console I have: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/meld/meldwindow.py", line 436, in on_menu_close_activate page.on_delete_event() File "/usr/lib/python3/dist-packages/meld/filediff.py", line 842, in on_delete_event del self._cached_match AttributeError: _cached_match Eventually tabs pile up and cannot be closed, except by closing Meld. $ lsb_release -rd Description: Ubuntu 18.04 LTS Release: 18.04 $ apt-cache policy meld meld: Installed: 3.18.0-6 Candidate: 3.18.0-6 Version table: *** 3.18.0-6 500 500 http://archive.ubuntu.com/ubuntu bionic/universe amd64 Packages 500 http://archive.ubuntu.com/ubuntu bionic/universe i386 Packages 100 /var/lib/dpkg/status ** Affects: meld (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1768369 Title: Tabs don't close after saving changes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/meld/+bug/1768369/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
