I installed Task Coach from this link:
https://software.opensuse.org/package/TaskCoach
When I try to open a pre-existing .tsk file from a Fuse mount (ssh on gvfs in
this case), it fails when locking the file.

Reproducible: Always

Steps to Reproduce:
1. Use Task Coach to open a file on a Fuse mount
2. 
Actual Results:  
Python stack trace appears in a dialog

Expected Results:  
The data should appear in Task Coach
