Comment 1 Seb Ruiz 2008-11-27 22:31:54 UTC

Unfortunately your backtrace is useless as it does not contain debugging symbols. Please install an amarok-debug package and reopen this bug report if you have a good trace.

Comment 2 AlfonsName 2009-04-27 14:10:20 UTC

Hi, I'm experiencing this bug again with amarok 2.0.2. as shipped with ubuntu jaunty and ampache 3.4.1 as shipped with debian lenny.

See https://bugs.launchpad.net/ubuntu/+source/amarok/+bug/367737 for a backtrace with amarok-dbg installed.

Comment 3 Mark Kretschmann 2009-04-28 08:49:48 UTC

@AlfonsName: The backtrace on launchpad is unfortunately _also_ without debugging symbols: It's easy to tell: There are no line numbers referenced in Amarok code.

See here for an example:

#1 0xb7956b67 in CollectionTreeItemModelBase::setCurrentFilter () from /usr/lib/libamaroklib.so.1
