BackupPC-debuginfo-3.1.0-15 contains no sources. Looks like 3.1.0-14.1 did not have this problem. See blocker bug for pointers to possible fixes; I suppose the suid bit at end of %install might cause this and the fix could be to not add the suid bit there but later in the %files section.
The problem does not exists before -15.fc14 release because of bug #611009 ; I had to add a C wrapper to avoid this issue. I've tried to remove the suid bit at %install ; that does not solve the issue. I wonder if disabling debuginfo for that is not the solution. If that is not, I'll need some help and/or advices, as I really have no idea what's wrong and how to fix that.
Well, nevermind... Thanks to Pikachu_2014 on IRC, I've understand what the problem is and how to solve it. The .c file is a separate source (Source4), and therefore is not included in the BUILD directory ; where the find-debuginfo.sh script is looking for it. I've fixed the issue copying the Source4 to the BUILD directory in the %prep section, the issue seems to be resolved this way. I'll commit the change and rebuild the package soonly.
