Unhandled exception when system file manager entry is malformed

Looks different to #1600786 as the Traceback is different...

program_version=0.9.24

When right-clicking on a thumbnail and selecting "Open in File Browser..." I get the following error:

ERROR An unhandled exception occurred
ERROR Traceback (most recent call last):

In the RPD log it says:
