Mixxx crashes with some mp3 after beat detect

[surfed]

this happens on some mp3's but not ogg files. Song will load, display waveform and crash. Sometimes it will close mixxx and other times just make it unresponsive. Turning Beat detection off fixes the crashing.
Output of console before crash:
Debug: file length 40188672
Warning: X Error: BadLength (poly request too large or internal Xlib length error) 16
  Extension: 129 (Uknown extension)

Getting this on various mp3,s. also beat detection is always on even when switched off in prefs. Another output:

Debug: file length 8460288

Hi surfed,
Can you please provide us with the following information:
- Mixxx version
- Linux distro
- Videocard
- Videocard drivers (nv/nvidia/ati/proprietary/open source, etc.)
- any extra details you think are relevant

Thanks,
Albert

Mixxx 1.6.0 Beta2 on Ubuntu Gutsy with NVidia GF5900Ultra and NVIDIA
drivers 100.14.19
Now it does this in some oggs as well. Its not the mp3 that triggers it
as i have not received this bug always on the same mp3.

I occasionally experience this problem with Kubuntu Gutsy AMD 64 - Nvidia 169.xx drivers also... I'm running with compiz-fusion enabled.

Are you running compiz-fusion surfed?

I also occasionally experience a problem a problem where one of my wave forms dies and the top 10th of my screen gets horizontal yellowish lines across it, until I terminate Mixxx. Mixxx works normally during that time accept for the 1 missing waveform.

I don't ever see these issues on my eeePC however (intel 810 video, no compiz/aiglx, kde 3.4.6).

I do have compiz-fusion enabled, will try without and report back.

Disabling Compiz has no effect, mixxx still crashes on some Files, seems very random. Debug states:

Debug: WaveSummary generation successful for "02 - My Culture (feat. Robbie Williams And Maxi Jazz).ogg"
Debug: BPM detection successful for "02 - My Culture (feat. Robbie Williams And Maxi Jazz).ogg"

and then it locks. Also note that Beat detection is turned off but still gets used?

I have had this and #197697 both occur. I cannot substantiate this, but I believe that this is related to bug #197697. BPM detection time is nearly simultaneous with waveform generation/display. I have been unable to make this bug hard-repeatable.

Fix committed in r1959 -- Apr 28 2008

The source of the XLib errors were the waveSummary generation thread writing UI updates. credit to this post: http://lists.trolltech.com/qt-interest/2005-05/msg00702.html

Apparently only the UI thread is allowed to update widgets, any other threads can occasionally trigger XLib errors which kill the UI thread.
