CRC mismatch in cyrus-sasl2-dbg

While trying to triage Ubuntu Bug #921489 I ran into a problem with debug symbols.

GDB prints:
Reading symbols from /usr/lib/sasl2/libgssapiv2.so.2...
warning: the debug information found in "/usr/lib/debug//usr/lib/sasl2/libgssapiv2.so.2.0.23" does not match "/usr/lib/sasl2/libgssapiv2.so.2" (CRC mismatch).

(no debugging symbols found)...done.
