File invalid_dirty_panel.patch of Package mc.8087

Author: Adam Majer <amajer@suse.de>

Bug: 1087708
Summary: other_panel can be invalid?

Reproducer is

1. set right panel to Information
2. edit and copy a text file
3. delete the file

valgrind seems inconclusive where the pointer was removed.
Seems it was already reused? Not setting other_panel dirty
bit doesn't seem to have any effect, and in worse case it
may cosmetic only...
