If it was built with a version of libz earlier than 1.2.4, this might either be
1) a bug in libz 1.2.4
or
2) a bug in Wireshark, where it was using libz incorrectly in a fashion that happened to work with earlier versions of libz but doesn't work with libz 1.2.4
as
1) somebody else had a similar problem with Wireshark on Gentoo Linux, and Wireshark was using libz 1.2.4 there
and
2) one of the changes in libz 1.2.4 was the "Wholesale replacement of gz* functions with faster versions", those being the routines Wireshark uses to read capture files when built with libz support.
Those routines are used even to read *uncompressed* files (the gz* routines in libz handle figuring out whether the file is compressed or not, and hides that from the application reading the file).
