Issue #1717 has been updated by tuxillo.

Description updated
Category set to VFS subsystem
Status changed from New to Feedback
Assignee deleted (0)
Target version set to 4.2.x

Hi Josepht,

It seems that it happened while pruning the fileystem.
Is there any way to reproduce this one? It seems weird to me that this would still be relevant and that none has reported it again.

Cheers,
Antonio Huete
