What do you mean with:
removable device entry ?

Did you edit your device partition table or remove a place from the PlacesView?

Have you been able to reproduce this bug recently?

thanks !

Closing this bug since it's been 10 months until feedback was requested.

We are suffering from crashes like this and we have all the intention to finally fix this issue but to do so we need feedback since no developer can reproduce the crash.

Please, if you find the time to provide feedback and the bug is still reproducible for you (we have fixed some similar crashes in the last month) please please, re-open the bug.

Thanks for reporting !
