I don't know what could be wrong. The code seems to correctly unlock the file.
Maybe we should log all unexpected exceptions to have more information the next time this problem appears again (simple fix in attached patch).

Reassigning to cnd/Debugger. Please consider applying the patch.
Thank you.
