New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.7.00 (4.7.0) using Qt 4.7.2

- What I was doing when the application crashed:

Was installing Amarok from source. Not sure is this is the cause, but a duplicate report to this one does suggest a problem while installing. Related to filesystem watching perhaps?

Reproducible with KDE 4.7.2 on Kubuntu 11.10, Qt 4.7.4. With all those duplicates I guess the bug is confirmed :)

Comment 25 Alex Fiestas 2012-04-22 03:40:57 UTC 
We are going to need more information if we want to fix this bug, please try to answer the following questions:

-How often is this bug reproducible?
-Is it always reproducible doing the same action?
-Execute: "solid-hardware list nonportableinfo" before and after the crash (attach the file)
-Distribution of using

Then, if you could run plasma-desktop with valgrind that would be fantastic (and probably what will make us fix this issue).

Thanks !

Setting libsolid component and myself as assignee
Comment 29 Alex Fiestas 2013-03-02 00:04:33 UTC 
Double checked, this one was fixed when fstab backend was fixed to emit deviceAdded/Remove din the right order.

Please if I'm mistaken and you are able to reproduce the bug feel free to reopen the bug!

Thanks !
