WebKitWebProcess WebKitGtk+ 2.4.8 uses memory without end when visiting some LinkedIn URL

[Andres Gomez (Tanty)]

Ubuntu 14.10 with GNOME3 PPA.

I launch Web, GNOME's default browser and I log in into my LinkedIn profile.

Then, from the top bar I place my pointer over the "Connections" menu so it is expanded, once expanded, I click on the "See all" link:
https://www.linkedin.com/people/pymk/hub?ref=global-nav&trk=nav_utilities_invites_header

Upon doing so, the browser freezes and I notice the HD of my computer starting to work hard. After checking with "top" the WebKitWebProcess is growing its used memory by the Gbs!!! and it doesn't seem to stop.

This may not be a problem in WKGTK+ but the graphics driver since, after repeating the process with a GDB attached to the WebKitWebProcess, GDB states that the point in which it exits when manually killing the process is:
/usr/lib/x86_64-linux-gnu/dri/i965_dri.so

However, I cannot reproduce with Chromium, FF (of course, the code path is completely different).

Description-en: free implementation of the OpenGL API -- DRI modules
 This version of Mesa provides GLX and DRI capabilities: it is capable of
 both direct and indirect rendering. For direct rendering, it can use DRI
 modules from the libgl1-mesa-dri package to accelerate drawing.
 .
 This package does not include the OpenGL library itself, only the DRI
 modules for accelerating direct rendering.
 .
 For a complete description of Mesa, please look at the
 libgl1-mesa-glx package.

Andreas Gomez, thank you for taking the time to report this bug and trying to help make Ubuntu better. However, the GNOME3 PPA is not a software package provided by the official Ubuntu repositories. Because of this the Ubuntu project can not support or fix your particular bug. Also, as per https://wiki.ubuntu.com/Releases , Ubuntu 14.10 is EOL as of July 23, 2015.

If this is reproducible in a supported release, please report this bug to the provider of the software package. Thanks!
