empathy crashed with SIGSEGV in g_closure_invoke()

[Joe Barnett]

Binary package hint: empathy

received a message from a contact and viewed in through the message indicator applet.

shortly afterwards, empathy froze for a second or two and then crashed. looks like a bunch of karmic bugs w/ similar crash, but this is w/ latest lucid package, so filing new bug.

the following sequence of events seems to trigger this crash very often:

0) double click a contact to open a new chat window
1) try to paste a url by middle clicking, where the selection is actually on another machine sharing mouse/keyboard through synergy
2) nothing shows up in chat window, so middle click again and see the url show up, and press enter to send msg w/ url in it
3) close chat window
4) wait some time, get the crash

not sure how synergy-specific the paste issue is, or if its even related? but seems to trigger it quite effectively.

marking triaged as its sent upstream. Thanks Joe for your bug report and sending it upstream.

[Joe Barnett (thejoe)]

can get the upstream patch applied to ubuntu packages? it at least bypasses the crash...

[Omer Akram (om26er)]

Joe I think empathy 2.30.1 will come in lucid updates once its released that would be right after Lucid gets out, I think.

[Omer Akram (om26er)]

Empathy 2.30.0.1 just got released so this will hit lucid soon
