crashes after some time: too many files opened

Binary package hint: galeon

After using Galeon some time (an hour or so? sometimes shorter if I do a lot of page refreshes), it either crashes or becomes unresponsive. Here's the output to std.err.:

----
I/O error : Too many open files

** (galeon:11104): WARNING **: Failed to save /home/kimiko/.galeon/session_crashed.xml
----

..possibly repeated a few times if it didn't crash right away and I tried to click a link a few times before noticing it not responding.
Here's a backtrace from gdb:

----
#0 0xffffe410 in __kernel_vsyscall ()
#1 0xb72037c3 in *__GI___poll () from /lib/tls/i686/cmov/libc.so.6

Using lsof shows that Galeon opens the same file many, many times: /usr/share/X11/locale/en_US.UTF-8/Compose
locale says:

Encoding in Galeon is set to 'Universal' and 'automatic', whatever that means.

I think I noticed this bug in Epiphany too once. I'll see if I can get output/backtrace for that too.
