Description Tim Waugh 2011-10-03 14:14:05 UTC

Description of problem:
Some printer drivers are not visible due to a CUPS issue with handling the PPDs cache.

Version-Release number of selected component (if applicable):
cups-1.5.0-10.fc16.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Install hpijs
2.lpinfo -m | grep f2200

Actual results:
Only one entry (for hpcups).

Expected results:
One entry for hpcups, another entry for hpijs.

Additional info:
It's some sort of memory handling issue.

valgrind /usr/lib/cups/daemon/cups-driverd list 1 0 ''
(as root) shows the problem in general:

Found while diagnosing bug #581656.
