3558	F5/F6/F7/F8 often doesn't report proper error	egmont		"Try to perform a copy, move, mkdir or delete operation that you do not have permission to.

The reason in the error dialog box is sometimes correct (e.g. ""Permission denied"", ""File exists"" etc.), but often is a literal ""(null)"", or the empty string, or some other garbage (e.g. a previous file name you operated on); followed by the numeric error code.

Looks like some serious memory corruption going on, which can potentially lead to other problems (e.g. crash) as well.

This is on Mac 10.10.5, I'll try on Linux as soon as I can.

Dates back at least to 4.7.5, haven't tried older versions."	defect	closed	critical		mc-core	4.8.15	invalid					no branch
