Description of problem:
enabling claws-mail-plugins-bogofilter makes it nag that bogofilter cannot be
run, which is no real surprise as the latter is not a dependency

Version-Release number of selected component (if applicable):
claws-mail-2.9.2-1.fc7.src.rpm

How reproducible:
it nagged once and then I installed bogofilter

Steps to Reproduce:
1. yum install claws-mail-plugins-bogofilter
2. run claws-mail
3. enable the bogofilter plugin
  
Actual results:
claws-mail complains that bogofilter cannot be run

Expected results:
Requires bogofilter

Additional info:
# rpm -q --requires claws-mail-plugins-bogofilter
claws-mail = 2.9.2-1.fc7
