Browsing a directory with a large png file can cause the system to almost hang

[Jonathan Moerman]

If I browse through a folder containing a very large png file (92340x22572) pantheon-files tries to render a thumbnail of this file, causing a very large spike in ram usage and, if I have something like chrome opened with a few tabs, slows the system down to a point where it is almost frozen. (mouse moves once every few seconds)
In this case libgdk pixbuf crashes after a few seconds with the following message in dmesg:

segfault at 7fb36b8a560c ip 00007fb579dbbce0 sp 00007fb5733a3838 error 4 in libgdk_pixbuf-2.0.so.0.3000.7[7fb579da8000+20000]

If the system hasn't enough free ram (<6gb free) it takes much longer to recover and, untill libgdk pixbuf crashes, will barely respond to the user.

I guess this isn't a coding flaw in pantheon-files it self, but that does not matter to the user...

Perhaps it is a good idea to modify pantheon-files to ignore pictures (only for thumbnailing, of course) if the amount of pixels exceeds a certain limit?
