Bug 394963 – www-client/opera-11.60.1185: Using a gtk3 application as mime-type, protocol, ... handler crashes the handler with „GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported”

• Status: RESOLVED DUPLICATE of bug 363387
• Product: Gentoo Linux

[Description Christian Aistleitner 2011-12-16 18:13:05 UTC]

The current ebuild www-client/opera-11.60.1185 does not allow the use of gtk3 applications to handle mime-types, protocols, ... -- even when compiled with gtk3 use flag.



Reproducible: Always

Steps to Reproduce:
1. emerge opera evince
2. Start opera using the provided launcher script /usr/bin/opera
3. Navigate to http://dev.gentoo.org/~dberkholz/stateofgentoo.pdf
4. In the dialog box, select „Document Viewer” (i.e.: evince) in the “Open with:” combo box.
5. Hit “Open”
Actual Results:  
Evince crashes even before visibly coming up. The line

  evince[4730] trap int3 ip:7f7d7670ac09 sp:7fff5259b5b0 error:0

gets added to the syslog.

Expected Results:  
Evince showing the pdf.

Putting strace between opera and evince, shows that the actual error message is

  Gtk-ERROR **: GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported

The culprit is line 174 (i.e.:
  echo 'export LD_PRELOAD="/usr/'$(get_libdir)'/libgtk-x11-2.0.so"' >> ${PN}
) in the ebuild file.
While the above line seems to fix bug #375939 for some, preloading this GTK+2 shared object, introduces GTK+2 symbols, for /all/ users for /any/ external program started by opera.

Hence any GTK+3 application started by opera (mime-handler, protocol-handler, ...) crashes.


After removing line 174 (i.e.:
  echo 'export LD_PRELOAD="/usr/'$(get_libdir)'/libgtk-x11-2.0.so"' >> ${PN}
) from the ebuild, and rebuilding, opera can launch GTK+3 applications without any problems.

I am not convinced, that the bugs are duplicates.

Bug #375939 is about getting flash to work. There, it's not even clear if the PRELOAD line works or applies. The bug is in unconfirmed state.

Bug #394963 is about getting some artificial dependence on GTK+2 out of the way to allow GTK+3 handlers.

Once bug #375939 is resolved, they might block each other. But the issues of the bugs are different. Hence, they are not duplicates
