I can confirm. I'm running a normal x86 system, the backtrace looks equal (apart from the lib64 library, mine is called tls)

Here is the last console output:

amarok:   [xine-engine] Metadata received.
terminate called after throwing an instance of 'std::bad_alloc'
  what():  St9bad_alloc
Very strange! got a DCOPReplyWait opcode, but we were not waiting for a reply!
Very strange! got a DCOPReplyDelayed opcode, but we were not waiting for a 
reply!


Here is the backtrace:

These backtraces do not appear to be caused by the same problem.  Not only that, but the second one seems to be running code that has been changed in SVN as of two days ago (even though that is the build date), and that cannot be run anymore.

Both of you please SVN up and rebuild, making sure to pass --enable-debug=full to configure...there's not much useful information in these backtraces.

If you still have similar problems, then please update.

Thanks!

OK, I reproduced it with svn r556730. I removed all previously installed amarok versions, did a make clean and compiled with full debugging options.

When switching to another song, Amarok crashes, but the music continues to play. The Amarok GUI is completely unresponsive, and also Kopete (which uses the nowlistening plugin), is completely unresponsive until I kill Amarok.

When the crash happens, actually two kmail windows open with two backtraces. I'll post them here:

I recompiled current svn yesterday, up to now there were no crashes.

libpng/xinelib crashes, as was dicovered through the e-mails.
