#1113 Crash/coredump with mounted USB/LUKS drive during file operation

[EnSER]

PCManFM 1.3.1 is crashing occasionally when I have an external 6TB USB drive with LUKS encryption mounted, mostly when a file transfer is done to that USB drive. The last crash happened during a large file transfer (117files/43GiB), when I emptied the "Trash Can"(erased deleted files).
It seems to me like some kind of delay was too great, so something crashed waiting for access/resources?

Additional info:
PCManFM version: 1.3.1
OS: Arch Linux

Steps to reproduce:
Mount external USB HDD with LUKS encrypted partition.
Transfer several GB of data in several files to that drive.
Erase deleted files from the same drive in parallel.
-I also got crashes without deleting anything in parallel, but I think this or any other parallel file system action(s) create the issue with a higher probability.
This issue can't be reproduced regularly.
