Rhythmbox Crashes with Sansa e260

[Stephan Rose]

Binary package hint: rhythmbox

Rhythmbox will crash when enabling the MTP plugin to sync with a MTP device or when the plugin is already enabled, it will crash when the device is connected.

Terminal Output:

Potential MTP Device with VendorID:0781 and ProductID:7420 responded to control message 2 with a response that was too short. Problems may arrise but continuing
PTP: Opening session
PTP_ERROR_IO: Trying again after resetting USB

Thanks for your bug report. Please try to obtain a backtrace http://wiki.ubuntu.com/DebuggingProgramCrash and attach the file to the bug report. This will greatly help us in tracking down your problem.

Unfortunately I was not able to obtain a backtrace. When I ran it with GDB it actually didn't crash that time. I'll try it again though when I get a chance this week as it seems that only my office computer is having the problem. My PC at home works no problem which is weird. Both are running Gutsy and both are up to date and both my desktop configurations are virtually identical.

Just by pure coincidence, I came across this bug and I think they might be related:

[Sebastien Bacher (seb128)]

not easy to say without a backtrace showing where it's actually crashing

[Stephan Rose (kermos)]

Well it started doing it here on my home computer as well. So it's happening on both machines now. It seems to be very sporadic as earlier today I was having absolutely no problems.

I'm working on obtaining a complete stacktrace but it seems I am still missing some debug symbols.

Here is what I have so far, I will try to track down the additional missing symbols and see if I can get a more complete trace.

Could you get a debug backtrace or let apport send the bug so it gets automatically retraced? That doesn't look like a duplicate

[Stephan Rose (kermos)]

If you can tell me how I'll be happy to do it. I can't send in a report with Apport because apport doesn't come up with Rhythmbox for some reason (works fine when other apps crash though).

[Stephan Rose (kermos)]

I found another MTP related crash when running mtp-files from the mtp-tools package. Maybe it's related. Apport came up for that so I filed a report.

We are closing this bug report as it lacks of a better trace, we need to investigate the problem further. However, please reopen it if you can give us the missing information and don't hesitate to submit bug reports in the future.

Hi guys

I am new to Ubuntu so I hope that I haven't messed this up. I followed the instructions to do the backtrace and I have attached the backtrace to this post. If the info isn't there please let me know and I will try again.
