Occasionally all emacs windows will stop responding to character input - though they will will respond to mouse clicks. Sometimes, I can recover by hitting ^G in all windows until one takes it. Other times, the only way out is to kill all emacsclient processes, at which point new emacsclient invocations can connect to the daemon and things work. Version-Release number of selected component (if applicable): emacs-23.3-4.fc16.x86_64 How reproducible: Happens daily, but not on command. Steps to Reproduce: 1. Run emacs with emacsclient 2. Suddenly notice it's ignoring you 3. Actual results: No response from emacs windows Expected results: The $#*$! thing should be listening to me. Additional info: I cannot reproduce the focus problem described in #674140, so I think this is a different bug.

Tried (fully updated) Rawhide with emacs-23.3-4.fc16.x86_64 and Emacs clients for a day and the issue didn't occur. I also use emacs-23.3-4 on Fedora 14 without any problem (using emacsclients occasionally). When the problem occurs again, could you attach gdb to the emacs daemon (via `gdb --pid PID`) and get the backtrace, please?

Hi Anders, thanks for fixing this bug. Seems the PPAs are backed up, your package still hasn't built. However, I verified it builds on i386 in pbuilder. I upgraded to glib 2.31 but was unable to reproduce the bug. However looking at the patch the error looks pretty obvious and the patch looks sane, so I've gone ahead and uploaded it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/902043 Title: emacs -nw freezes with 100% CPU with glib 2.31 To manage notifications about this bug go to: https://bugs.launchpad.net/emacs/+bug/902043/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
