Need help with kde-partitionmanager and kdelibs in F18

[Mattia Verga]

I've just found that kde-partitionmanager in F18 no more works...
I tried to make a new build in koji with latest upstream svn version, 
the build process went fine, but kde-partitionmanager still doesn't 
work: it doesn't find devices in the correct way (it shows random disk 
partitions as devices instead of showing the disk itself).
Based on a discussion with the upstream maintainer and the fact that in 
F17 it works, the upstream maintainer thinks it's a problem related to 
the use of udisks2 in F18 (while F17 uses udisks1). Here you can find 
the discussion:
https://bugs.kde.org/show_bug.cgi?id=311408

Now my problem is: how can I make a working build in F18 and Rawhide? Is 
there any way to force the use of udisks1 in my package, or it's a 
choice that can only be made in kdelibs?
