Hey, thanks for the report, I'll take a look.

Fixed upstream by ccca105, this will be released in dnf-0.4.11.

Another user experienced a similar problem:

Latest version of DNF crashes when searching for something which cannot be found.
E.g. searching for 'rockbox' by typing
$ dnf search rockbox
this is always reproducible for me with any random search string that cannot be found. This is reproducible as default user and as root.

reporter:       libreport-2.1.10
cmdline:        /usr/bin/python /usr/bin/dnf search rockbox
