[CentOS] AcroRead failing miserably in CentOS 5.0

I could swear that this was working just last week, but now when I run
the Adobe Acrobat reader, it hangs.  If I run it "directly"
(/usr/bin/acroread) with -DEBUG as the first argument, I get an
infinite loop of:

expr: syntax error

I tried removing and reinstalling it, but no change.

Any ideas?
