Description François Valenduc 2012-05-05 07:27:45 UTC 
When I filter my music collection while a MTP device is connected, amarok crashes instantly. I am using libmtp-1.1.2 and amarok-2.5.0-r2 from gentoo.

This is the output I have got while starting amarok from a terminal (with --nofork and -d):

*** glibc detected *** amarok: double free or corruption (fasttop): 0x00007f42143e1690 ***

KCrash: Attempting to start /usr/lib64/kde4/libexec/drkonqi from kdeinit
sock_file=/home/francois/.kde4/socket-pc-francois/kdeinit4__0
zsh: suspended (signal)  amarok --nofork -d

Reproducible: Always

Steps to Reproduce:
1.Start amarok
2.Connect a MTP device (creative Zen X-Fi if that matters)
3.Filter the local music collection
Actual Results:  
Amarok gives a segfault and crashes.

Expected Results:  
Amarok should'nt crash.
Comment 1 Myriam Schweingruber 2012-05-06 11:33:52 UTC 
Could you please provide a backtrace for the crash? Else this report is not useful.
Comment 2 François Valenduc 2012-05-06 12:10:23 UTC 
So I followed the informations found on http://amarok.kde.org/wiki/Debugging_%28documentation%29#GDB and I get this:

Comment 3 Myriam Schweingruber 2012-05-06 22:26:26 UTC 
Thank you for the backtrace. Could you please provide exact steps on how to reproduce this?
Comment 4 François Valenduc 2012-05-07 17:12:16 UTC 
I tought I was sufficiently clear. So I repeat the way to reproduce the crash
1) Start amarok
2) Connect an MTP device
3) Enter something in the filter box to search for tracks in the music collections (local and on the device). As soon as I have typpen something, amarok crashes.
Comment 5 Myriam Schweingruber 2012-05-08 11:06:16 UTC 
Thank you for the information. This is apparently an old bug refacing. I reopened the other one and marked it as a regression.
