Hi,

Hi,

Thanks for taking your time to answer.

 

can you confirm that this happens with HTML emails which have images? If so,
then you are probably affected by bug #686810 [0].

No, it does not appear to be associated with HTML emails. 

Otherwise, make sure you have -debug packages for Evolution, Gtk+ and glib
installed and attach GDB to Evolution:

gdb /usr/bin/evolution `pidof evolution`

and get a full backtrace:

 thread apply all bt

Ok. I'm not sure if I'm doing this right. I ran the command as above (including the `pidof evolution` string; should there be an actual PID in there?). Once gdb is started I type run to start Evo. Evo after 30 min or so hangs with a number of jobs (including some Unknown ones; see attached screenshot). At the same time Evo was downloading emails (8 pop accounts). Evo then froze and was unresponsive to me pressing any of the cancel buttons. CPU utilization was 100%. Only way to shut down Evo was to kill it manually.

After Evo was killed I typed in your last command, and got in return a blank line.

Am I doing something wrong debugging Evo, or is this the expected behavior when the app is killed? Sorry if if this question is lame, but I have no idea what to expect with the process you outlined.

Sorry for posting this again.

The problem outlined above is recurring (mutliple times per day). It seems to start with a task called "Saving user interface", at which point Evo freezes. At least twice this happened in conjunction with a 'Retrieving Message xxxxx' message shown in the message pane (which never disppears). CPU goes to ~50%. Gradually, a whole bunch of 'Unknown' tasks are spawned; seems CPU usage then goes up eventually hitting 100%.

I'd like to file a bug report, but due to my apparent inability to use the gdb tool properly am unable to do so.

Can someone point out for me further directions for debugging this issue?

Thanks.
