Access violation on scroll

[zorblek]

I keep getting an "Access violation" error with easymp3gain on Ubuntu Lucid. Steps to reproduce:
1. Run easymp3gain
2. Add a music folder to the list
3. Scroll down the list. Eventually an access violation error appears.

This bug makes easymp3gain nearly unusable unless I want to risk data corruption.

Same for debian

This error is already known: http://sourceforge.net/tracker/?func=detail&aid=3008674&group_id=207001&atid=999854
The problem is that the widget abstraction layer easyMp3Gain uses does not work correctly with newer GTK+ versions. We wait until the package "lazarus" (lcl-gtk2 in this case) is released in version 0.9.30. Then this bug should be gone.

[Matthias Klumpp (ximion)]

Bug is fixed in Ubuntu Oneiric and Debian Sid / Testing.
Thanks for your bug report! (You can fetch an updated package from Debian, providing a backport for Natty won't be possible cause the dependency chain has changed a lot)

This bug is back in Quantal.
