Bug#506882: kpdf: crashes on some large file

Package: kpdf
Version: 4:3.5.9-3
Severity: important

I got a 20MB file with large index and loads of graphics which crashes
kpdf at least half the time I open it. It's Oracle's SQL reference.

Here's the message after running it:

kpdf: ../../src/xcb_lock.c:33: _XCBUnlockDisplay: Assertion
`xcb_get_request_sent(dpy->xcb->connection) == dpy->request' failed.
KCrash: Application 'kpdf' crashing...

and here's the stack-trace:
