What is the problem?
modules in crash reports lists libraries more than once if they're loaded
for readonly, executable, etc because each mode gets its own listing in
/proc/self/maps.

What is the expected behavior?
Modules should only list files once

What happens instead?
Most modules are listed more than once resulting in a list that's at least
twice as long as it should be.

This might be fixed since the Breakpad client got rewritten a while back.
