Just had some time in the last two days, and here's the list of uploaded NMUs. So far, I had only one maintainer complaining (again, sorry!), but I must admit that on Sunday I just didn't follow the correct NMU procedure 
Anyhow, here's what I have:
- #504824 [libnids] FTBFS with GCC 4.4: #elif used instead of #else
- #504864 [omnievents] FTBFS with GCC 4.4: missing #include

Some highlights
Most of these bugs, if not all, already had a patch attached. Thanks to Martin Michlmayr for his work on this!
Regarding fusecompress, after my upload to DELAYED/2, the maintainer promptly replied asking for sponsorship of a package he already had. So this does not really count 
If you want to participate in this great game too, and improve our loved distribution, you can have a look at this list of possibly easy bugs to fix.
Have fun!
