As I just upgraded my laptop from FC19 to FC20 I also found out that there is a new KeePassX alpha version.
So I tried to build a new rpm and found out that my spec file I had put online was not working. Apparently the last time I uploaded it it got corrupted. To get the new rpm files I had to fix my own mistake.
Because of this fix I uploaded the spec file now as a file and also described the steps to build a new rpm.
If you want to build your own rpm you can use my spec file and build description. You can then create your own i386 or other alpha version without problems.
