Freeze on MTP transfer

[Salamandar]

Well I was transfering some 11GB on my phone and at 10GB Sunflower froze. Fortunately it was launched in a terminal and the traceback is :

Exception in thread Thread-15:
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 801, in __bootstrap_inner
    self.run()

  File "/usr/share/sunflower/application/plugins/file_list/gio_wrapper.py", line 73, in write
    self._resource.write(buff)
Error: Erreur libmtp : Erreur inconnue.

EDIT : Hm, and ctrl+C in the terminal returned :

^CTraceback (most recent call last):
  File "/usr/share/sunflower/Sunflower.py", line 75, in <module>

KeyboardInterrupt

but did not close SF.

Sunflower didn't close from Ctrl+C because GUI is started in separate thread. But I didn't expect error not to be caught there. Hm, strange. Thanks for reporting this. I don't know what would cause interruption during writing.

It may be a simple error in libmtp not managed in SF. Or a MTP error not catched in libmtp.

I think this was an issue in upstream library. I tried testing this with version 0.4 and couldn't reproduce. For this reason I am closing this issue. If it's not fixed, please reopen.

Thanks!
