Some applications crash on my Ubuntu 14.04.2 (all updates installed) with referring to the same source: libwebkitgtk-3.0.so.0.22.14

The relevant part was told me to be this:

Program received signal SIGSEGV, Segmentation fault.

This is the important backtrace of the Thread 1, “which caused the termination”.

I am assuming this started with update of libwebkitgtk-3.0-0 from version 2.4.0-1ubuntu2 to 2.4.8-1ubuntu1~ubuntu14.04.1, but I am unable to downgrade via synaptic or apt because the dependencies wants me to uninstall half of the system then...

This is my current kernel:
nsk@sesta09:~$ uname -a
Linux sesta09 3.13.0-48-generic #80-Ubuntu SMP Thu Mar 12 11:16:15 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
nsk@sesta09:~$ 

But the behaviour did not changed with the last kernel upgrade.

I am using Gnome Flashback desktop environment with version 3.8.0-1ubuntu12.2

Additionally using compiz

nsk@sesta09:~$ compiz --version
Compiz 0.9.11.3
nsk@sesta09:~$

Thanks to the help of Paul Menzel in this bug report, I was able to produce those debug traces: https://bugs.webkit.org/show_bug.cgi?id=142692
