Bug#342658: libqt4-core: QFile::open is unusable on ia64

[Jeremy Laine <jeremy.laine@m4x.org>]

Package: libqt4-core
Version: 4.0.1-5
Severity: important

I noticed that the ia64 buildd was unable to compile the package
'sailcut', it systematically hangs when running lrelease. Upon closer
inspection, it turns out that lrelease hangs when making a call to
QFile::open.

I tried compiling a minimal Qt4 program that makes use of this function
and sucessfully reproduced the problem. I have attached the program to
this bug report.

Cheers,
Jeremy
