Eli, I can reproduce this like this,
  tmp/
    one/
      uut.c uut.h
    two/
      uut.c uut.h main.c

If I compile each file in there own directory with -g and then link in
directory two/ and then start GDB from there, the command
  b uut.c:5 works for me and b ./uut.c:5 doesn't. If I compile 
gcc -S uut.c in either directory, the assembly file says the name is
"uut.c". Is there a better way to tell you what the debug info says?
