Red Hat Bugzilla – Bug 456475
Multiple PDFs display in separate evince windows instead of in firefox tabs
Last modified: 2009-08-30 11:58:58 EDT
Normally when I middle-click on a PDF link in firefox, a new tab opens and an
embedded evince window appears there and displays the document. But sometimes
if I open multiple PDFs (perhaps especially if I do so in quick succession),
some of the tabs don't display properly. Evince opens up in a separate window,
which I don't always notice. When I click on the tab that I was expecting the
PDF to appear in, I just see the content of whichever tab I was viewing before
that one. This is very confusing and can lead to closing the wrong tabs.
I'm sure where the bug is, but I'm using:
nspluginwrapper-1.1.0-4.fc9.i386 may also be implicated.
I can confirm this bug.
No matter what type of PDF viewer I try to embed (okular, evince, xpdf) I get the same result - an empty tab is opened (or the existing one is blanked-out), but the actual application is opened in a new window.
+1, also affects Firefox.
Looks like a duplicate of bug # 385831.
Has this been reported upstream to the mozplugger devs? Maybe update to 1.10.2 which was released in half a year ago?

I have the same problem.
This looks like a duplicate of bug #470509.
I experience this on Fedora 10 x86_64.
This bug is reported upstream against mozplugger:
As I understand it, evince has a stupid command line behaviour that is undocumented and this means mozplugger cannot handle it. So Fedora should be configured so mozplugger is not asked to handle evince.
Here's the problem:
When an evince command is run (more precisely, when /usr/bin/evince is exec'ed), it checks to see if another process is running evince. It may only consider such a process if it has matching characteristics such as UID or same display -- I don't know.
If such a process exists, the "work" is passed onto to the older process AND the newer process immediately exits. So mozplugger will be confused: the process doing the display isn't the process that it fired up.
If such a process does not exist, this evince does the work. But there is a twist: if another evince passes our evince process some more work, our evince won't exit until all the displaying is dismissed. Again, very confusing to the invoker.
This evince behaviour cannot be managed by mozplugger. So the configuration of Fedora should not let mozplugger handle .pdf files OR not tell it to invoke evince.
I think that evince's behaviour is quite wrong. It violates conventional expectations of command line behaviour. It is not documented. I fear it has security implications (eg. does it check that all evince invocations have identical privileges?)
i cannot reproduce this with 1.12.1. It seems the issue is fixed in this version
Seems to work just fine under F11.
