debug mode output

Since the last system update, amarok doesn't work. I can't get stack trace in spite of installing all debuginfo packages (gdb says: "No stack" when trying "bt" or "up" commands after the crash). The splashscreen blinks for a split of second and it crashes without displaying the main interface or systray icon. 

System info: 
$ uname -a
Linux cheeky.at-home.net 3.3.6-3.fc16.x86_64 #1 SMP Wed May 16 21:43:01 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

$ cat /etc/redhat-release 
Fedora release 16 (Verne)

$ amarok -v
Qt: 4.8.1
KDE Development Platform: 4.8.3 (4.8.3)
Amarok: 2.5.0


The output in debug mode is in the attachment.
Comment 1 Myriam Schweingruber 2012-05-26 16:09:15 UTC 
Could you please run Amarok in gdb with like follows:

gdb amarok
run -d --nofork

once it crashes, type

thread apply all backtrace

and provide only the konsole output after the crash.

gdb output 2

There seems to be no backtrace available... See attachment.
Comment 3 Marek 2012-05-26 19:05:43 UTC 
Just noticed that I missed the second dash in "--nofork". Will post more info.

more info from gdb

Here it comes. I omitted most of output before the crash.
It looks like something about building a MIME type list.. (line 82).

You should also install the amarok debug symbols, you don't have them currently. In Fedora just do
debuginfo-install amarok

Thank you for the feedback. My bad, apparently I wasn't looking well enough.

Comment 10 Marek 2012-05-28 20:42:46 UTC 
It seems this bug was introduced in 2.5.0-8 (current Fedora 16) version. After downgrade (via yum) to 2.4.3-1, amarok starts OK. Or the code just takes a different path ;-)
