Icecat crash

[Danny Milosavljevic]

Hi,

so I've finally found a 100% reproducible way to crash icecat. Previously it 
has been sporadic and not reproducible.

Try going to this site in a new icecat (guix master) instance:

http://arstechnica.com/security/2016/12/this-low-cost-device-may-be-the-worlds-best-hope-against-account-takeovers/

Scroll down. It will crash. Every time.

I think I saw a libjpeg warning somewhere when updating. Also, I get:

[20912] ###!!! ABORT: X_CopyArea: BadDrawable (invalid Pixmap or Window 
parameter); 3 requests ago: file 
/tmp/guix-build-icecat-45.5.1-gnu1.drv-0/icecat-45.5.1/toolkit/xre/nsX11ErrorHandler.cpp,
 line 157

The X graphics driver is

[    31.045] (--) intel(0): Integrated Graphics Chipset: Intel(R) GM45

.

I did reconfigure Guix today - so it's quite current.

Backtrace is

That reminds me, is there a way to have debug symbols in icecat:debug or 
something? What's our plan there?

I see the comment about it needing 5 GiB - but it doesn't have to be installed 
by default or anything...
