Bug#799275: [GDK] patch - avoid integer overflow when allocating a large block of memory

[Vlad Orlov]

Source: gtk+2.0
Version: 2.24.25-3
Severity: serious
Control: tags -1 jessie patch
Control: affects -1 eom


Due to a logic error, an attempt to allocate a large block of memory
fails in gdk_cairo_set_source_pixbuf, leading to a crash of the app
that called it, for example, eom [1].

This issue had been fixed [2] in GTK+3, but the commit never made it
to GTK+2 branch. I've converted it into a patch for GTK+2.

The debdiff is in the attachment. Please apply it in Jessie.
