To reproduce: mkdir test touch test/foo Run xffm Select both test and test/foo and hit delete Both items are deleted but xffm prints up an error about not being able to delete foo as it's already gone.
Selecting both test and test/foo and hitting delete is an erroneous behaviour by part of the user and should be warned. There is no harm done in waving a flag for the user. Anyways, the current default for xffm is now the iconview where the described behaviour is not feasible (you cannot select parent and child at the same time) so there should be no problem with this in the next release of xffm.
Fair enough. I'll tell the user you're uninterested in fixing this bug. Thanks for your time
Not uninterested. Just don't have the time for it at the moment. I'm open for any patch submission.
