Description

[Martin Mokrejs]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:36.0) Gecko/20100101 Firefox/36.0 SeaMonkey/2.33.1
Build ID: 20150425185639

Steps to reproduce:

This seems similar to bug #1126658 . I was opening a PDF file from http://mbe.oxfordjournals.org


Actual results:

For application/pdf found plugin npwrapper.nppdf.so

So, this can be reproduced in browser window by file://tmp/blah.pdf . In my case the PDF is NOT opened but instead, "Activate evince browser" icon is shown. At the same time, the ASSERTION is logged.

I have app-text/evince-3.14.2-r1 installed on my Gentoo Linux (64bit with multilib support). Seems I originally used Adobe PDF plugin 9.5 and it gave same ASSERTION. So is this ASSERTION independent of the actual plugin?

Resolving old bugs which are likely not relevant any more, since NPAPI plugins are deprecated.
