Description Dale Snell 2010-01-03 17:09:43 UTC 
abrt 1.0.0 detected a crash.

How to reproduce
-----
1.  Open Configuration panel, select Volume Control Plugin
2.  Select the relevant audio device
3.  Move the various sources/sinks to different places and click "Apply".  Boom.

Comment
-----
The only thing I did this time that I haven't done before is changing the ordering of the various sinks and sources.  I moved "PCM", "CD", and "Capture" to be just below "Master", and in that order.  When I clicked on "Apply", GKrellm died.  A small xmessage dialog appeared, with the message "gkrellm segmentation fault: Volume Plugin (apply_config)".  Then the abrt icon showed up, and here we are.  The error is repeatable.

Another backtrace

I can reproduce, here's another more informative backtrace.

This might be a bug in the gkrellm volume plugin (from the gkrellm-volume package which I maintain), not necessarily gkrellm itself.

When moving things up and down, I observe that the "Shown Name" column becomes empty/is lost for the just moved item, and I suppose that's where it later crashes in the volume plugin where it does some name comparisons when applying the changes.  I'll try to look into this more later (no time right now) unless someone beats me to it (and help is of course welcome).

A workaround seems to be that whenever an item's "Shown Name" column becomes empty when moving it, double click the Shown Name column again and re-enter a name for it before clicking Apply.  For some reason not all items' Shown Name column can be edited though.  And sometimes something else than the Shown Name gets actually shown for that item in the gkrellm GUI...
Comment 3 Hans de Goede 2010-01-04 09:33:16 UTC 
Mocing this over to gkrellm-volume for now, feel free to kick it back in my direction if it turns out to be a core gkrellm issue after all.

Please try this build when it becomes available in updates-testing, and report your results in the updates system.  It fixes the crash for me, but the config view still does not follow the configured order of the devices when the view is reopened (reported upstream), anyway the configured order is respected in the actual GKrellM UI.
