Description of problem:
When trying to parse Xorg server backtraces (e.g., see https://bugzilla.redhat.com/show_bug.cgi?id=712540#c10) I am running addr2line to get line of the code corresponding to the particular address. Quite often I make addr2line. I can make it fail even on the command line. E.g.,

addr2line -fe /usr/lib/debug/lib64/libc.so.6.debug 0x12dff1


Version-Release number of selected component (if applicable):
glibc-2.14-2.x86_64
binutils-2.21.51.0.6-2.fc15.x86_64

How reproducible:
100%

Steps to Reproduce:
1. see above
2.
3.
  
Actual results:
add2line crashes

Expected results:
it shouldn't ... my command could be stupid, I may ask to get some nonsense, but addr2line should kick me out decently.
