Comment 30 for bug 258504

> However, I have checked and many other pdf docs still don't load.

with the same console messages as you reported in bug #548746? If it is a different error - as you downgraded to poppler 0.12.0 it is not likely to be related to that poppler version conflict (ABI mismatch) anymore - these failures should be reported separately IMHO. Please do search the bug database beforehand - there are several other open bugs about issues when opening/importing PDF files. If you file a new report please attach any console messages or available backtraces as well as sample files that fail to load so that we can try to reproduce it on other systems.
