Comment 1 Myriam Schweingruber 2015-08-04 09:43:09 UTC 
Could you please also install debugging symbols for libgpod? The crash seems to occur in that library, not in Amarok.

See these lines:

Comment 2 joseph.m.pence 2015-08-04 23:48:43 UTC 
Hello,

What command(s) would I need to run to install the debug symbols for libgpod?
Comment 3 Myriam Schweingruber 2015-08-05 00:47:34 UTC 
If there are debugging symbols, those would have the same name as the libgpod package,  with the extension -dbg (depending on the distributions this can vary).

Both the iPod Touch and the iPhone have only a limited support in the libgpod library, the newer the device, the more likely it will not work I fear.

Does the crash only occur if you connect the device or does Amarok also crash if you start it with the device already connected?
Comment 4 joseph.m.pence 2015-08-05 02:58:45 UTC 
Created attachment 93898 [details]
ifuse error
Comment 5 joseph.m.pence 2015-08-05 03:03:17 UTC 
I don't seem to have a -debug package, I do see 6 support packages:
libgpod-cil
libgpod-cil-dev
libgpod-dev
libgpod-doc
libgpod-nogtk-dev
libgpod4-nogtk

I tried doing a sudo apt-get install libgpod-debug but it returned that no package was available, I apologize if there is some other command I could try that I am not familiar with.

Amarok crashes with the error I initiated the ticket with if I have the iPod already plugged in, if I don't already have the iPod plugged, Amarok gives the ifuse input/output error I attached.
Comment 6 joseph.m.pence 2015-08-05 03:10:23 UTC 
It's also worth noting that in the case where Amarok crashes (if the iPod is plugged in), I am able to navigate into the iPod dirs on the mount point.
Comment 7 Myriam Schweingruber 2015-08-05 12:10:16 UTC 
Thank you for the feedback.
Comment 8 Andrew Crouthamel 2018-10-31 03:51:59 UTC 
Dear Bug Submitter,

This bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond.

Thank you for helping us make KDE software even better for everyone!
Comment 9 Andrew Crouthamel 2018-11-12 03:23:07 UTC 
Changing back to REPORTED per request of Myriam (Amarok dev).
Comment 10 Justin Zobel 2020-12-17 05:38:54 UTC 
Thank you for the crash report.

As it has been a while since this was reported, can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved.

I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved/worksforme" when you respond, thank you.
Comment 11 Myriam Schweingruber 2020-12-17 15:37:42 UTC 
Closing as this is about an obsolete Amarok version, and there never was better support for the device upstream anyway.
