lastfm hangs

[Daniel Hahler]

Binary package hint: lastfm

After some time of playing, lastfm appears to hang (first sound hickups occur, then it's silent):

Letting it run again for a few seconds, gdb bt shows this diff:

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!
