[Kubuntu 9.04] Amarok crashes if an input file is given.

[Rafael Belmonte]

Binary package hint: amarok

Amarok crashes when it receive an input audio file.
Command amarok file.mp3 cause amarok to crash.
When I open in Dolphin a MP3 audio file, it is expected to be open with amarok, but amarok crashes.

This is not happening always.

It seems that after debugging the program, it does not crash.

The problem occurs when amarok is not started.

I obtain the following log when I do this :
1. Open a terminal
2. type amarok <path to any mp3 file>

As I do not have a debug-compiled amarok so I can't report the backtrace.
I guess the problem is the same as the one occuring when you double-click on a MP3 file in dolphin and amarok is not started.

Could you please obtain a backtrace by following the instructions at https://wiki.kubuntu.org/Backtrace please? Thanks in advance.
Testing with 2.1 would be welcome too.

I'm having the same problem on Kubuntu Karmic 9.10 with ppa:kubuntu-ppa/backports enabled

gdb reports nothing...

(gdb) backtrace full
No stack.
(gdb) info registers
The program has no registers now.

Anyway here is a backtrace from crash reporting assistant:

I found that amarok works for a user and doesn't work for another, so I made some testing:

- Create a new user -> Amarok works

On user that was crashing

- remove amarok cofig files -> nothing changes
- remove .kde folder -> nothing changes
- remove .xine folder -> Amarok works again...

So it must be a xine related problem

but then, after running amarok, restoring the old .xine folder, doesn't crash anymore.

Anyway a quick fix for people having this issue could be deleting the .xine folder in home directory

[Jonathan Thomas (echidnaman)]

Please file a separate bug report at bugs.kde.org against phonon. It is unlikely that this and the original crash are related.
