Bug#598739: evince: memory leak when trying to select text in a pdf

[Mathias Kende]

Package: evince
Version: 2.30.3-1
Severity: important
Tags: squeeze

When I try to select text in "image based" PDF the memory use of evince start
to grow fast until the system becomes unusable. In the meantime evince will
also not respond to user interaction.

Step to reproduce :
1 - open some PDF with bitmap text (I am not familiar with the PDF technology
so I don't know exactly how to describe this sort of non-modern PDF file).
These files will triger this bug :

2 - Try to select some text using the mouse cursor.
Nothing will happen, or a small amount of text will be highlighted.

3 - The memory used by evince will start to grow fast (around 50 or 100MB/s).

I am attaching a valgrind report of this bug. I don't know if it is accurate as
I am killing memcheck manually (before the complete freeze of the UI when the
system starts to swap too much). Also to pace of memory allocation is a lot
slower with valgrind.
