[Reportbug-maint] Bug#804130: reportbug: Crashes when filtering a list twice

[Dominik George]

Package: reportbug
Version: 6.6.5
Severity: normal

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

reportbug reproducibly crashes when doing the following:

 1) try to report a bug on a package
 2) use 'f' to filter the list of found reports
 3) use 'f' again to apply another filter to the filtered list
 -- I think it breaks here --
 4) select a bug report, read it
 5) use 'x' to append a message to the report

Traceback (most recent call last):
