[Dapper] Sound-juicer crashes after editing gconf keys

[ian marcinkowski]

In order to obtain properly tagged/named files, I'm required to go into gconf and manually edit the file-naming scheme that sound-juicer uses (which is a bug in its self, IMO).

Since doing a fresh Dapper Flight 6 install last week, I havn't ripped any CDs, until now.

After going editing the file_pattern and path_pattern keys, sound-juicer now crashes when I try to access the preferences dialog even though I've changed the gconf keys back to their default settings.

The following is generated by bug buddy:

[Daniel Holbach (dholbach)]

Thanks for your bug report. Which values did you put in there?

[ian marcinkowski (ianmarcinkowski)]

I changed:
base_uri
from: file:///home/ian -to- file:///home/ian/Desktop
device
from: <no value> -to- /dev/hdd (though I changed this back after this bug reared it's head)
file_pattern
from: %tn - %tt -to- %aA - %aT - %tN - %tT
paranoia
from: 8 -to- 255

I've since changed all values back to their defaults and sound-juicer is still crashing.

[Sebastien Bacher (seb128)]

Could you get a backtrace with libglib2.0-0-dbg installed?

[ian marcinkowski (ianmarcinkowski)]

I installed libglib2.0-0-dbg and got a rather small backtrace:

Reading the middle section, I just remembered that I changed the vorbis quality in the 'lossy' profile from 0.2 (or something) to 6. Perhaps that has something to do with the crashing.

The segfault happens right when I try to access the prefs dialog.

[Sebastien Bacher (seb128)]

The quality value is probably a different issue. Can you try to get a backtrace after update libglib2.0-0-dbg? The dbg package was not a debug one for some days but that is fixed now

So according to the backtrace the interesting value is optimized ...

Maybe you could rebuild the gconf2 package with debug (https://wiki.ubuntu.com/DebuggingProgramCrash) to figure what gconf key is the issue?

bug #42602 is a duplicate pointing to http://bugzilla.gnome.org/show_bug.cgi?id=339089 upstream

Comment from upstream:

"Hm, I can't replicate this at all. :/

Can someone who can grab the source and start by printing the values of active

Is anybody still have that issue with edgy?

anybody still having the issue?

[Ian Marcinkowski (marcinkowski)]

I'm not having this problem anymore. This problem disappeared a while ago, though I don't think I did anything special.

*shrug*

I'm still running Dapper if that matters.

Marking as fixed then. Feel free to reopen if you get the issue again
