Bug#696325: unblock: qt4-x11/4:4.8.2+dfsg-6
Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: unblock
Please unblock package qt4-x11
This last upload fixes the FTBFS we had on ia64 [0].
I'm including two debdiffs:
- qt4-x11_against_sid.diff represents the changes in the last upload wrt the
previous one.
- qt4-x11_against_wheezy.diff represents all the changes wrt wheezy, including
previously unblocked uploads.
[0] JFTR, it seems to be a bug in gcc with precompiled headers.
