Please re-run against CVS head to see if the mem leak patches from Carlos fix
these leaks.

Bugzilla Upgrade Mass Bug Change

NEEDSINFO state was removed in Bugzilla 3.x, reopening any bugs previously listed as NEEDSINFO.

Hello Christian,

can you still notice this issue with more recent Poppler versions?

Seems to not occur anymore.
