File 2.4.4-label-failure.patch of Package bacula

[label-failure.patch] IQ
 This patch should fix the problems labeling a tape while
 Bacula is requesting you to mount or label a new tape.
 It should also fix problems where Bacula will not recognize
 that a new tape is inserted or created and it keeps asking for
 a different tape. It fixes bug #1227.

Apply it to 2.4.4 (possibly earlier versions) with:

cd <bacula-source>
 patch -p0 <2.4.4-label-failure.patch
 ./configure <your-options>
 make
 ...
 make install
 ...
