Bugzilla Bug 220038

Audacity crashes with FPE when entering Preferences. The bug is traced in
audacity bugzilla but it seems to be gentoo-specific. Oryginal bug reports
contain stacktraces etc. 

Exception is triggered in gtk function gtk_label_get_angle(GtkLabel *label)

I case you've missed bug's URL field here's the link again:
http://limpet.net/audacity/bugzilla/show_bug.cgi?id=282

are we sure this is an audacity issue and not a wxgtk / gtk issue ?
can you try with latest stable  (1.3.4-r3) or 1.3.5, it uses wx 2.8 perhaps
that'll help and we'll probably get more support for this release than the 2.6
version

this is media-sound/audacity-1.3.4-r3 linked against wxgtk 2.8

With latest 1.3.5 it's the same:

Seems to be solved media-sound/audacity-1.3.5 (or the 'debug' USE flag as I
have just removed this flag)

Just installed: 1.3.5-r1, but i still get FPE when entering preferences.

Compiled using: alsa flac jack ladspa libsamplerate mp3 vorbis

Tried to switch through:
  [1]   gtk2-ansi-release-2.6
  [2]   gtk2-unicode-release-2.6
  [3]   gtk2-unicode-release-2.8

emerge --info here: 
http://pastebin.com/f5c27369a

Same here,
Also, i get that error when i try to export an mp3 too.

What USE flags are you using for lame package ?

Mine :
 - - debug   : Enable extra debug codepaths, like asserts and extra output. If
you want to get meaningful backtraces see
http://www.gentoo.org/proj/en/qa/backtraces.xml
 + + mmx     : Adds support for optimizations for Pentium MMX and Athlon class
processors
 - - mp3rtp  : Build the mp3-to-RTP streaming utility. **UNSUPPORTED**
 - - sndfile : Adds support for libsndfile

(I've no more seen this problem for several months)

Here:
# emerge -pv lame

I can't reproduce the problem with latest versions of Audacity
(media-sound/audacity-1.3.7).

Is there someone who still reproduces the problem ?

Yes I have it with =media-sound/audacity-1.3.7 with USE="alsa ffmpeg flac
id3tag ladspa libsamplerate midi mp3 soundtouch twolame vamp vorbis -jack"

It is still there for me in audacity-1.3.8 
both at requesting preferences or exporting mp3
