Comment 4 for bug 297831

Got the same bug under SunOS 5.10 Generic_127112-11 i86pc i386 i86pc with Python 2.6 and version 1.9 of bzr.

Moving _readdir_pyx.so out of the way as suggested fixes the problem for me.

A chdir() syscall with an empty string as argument (directory name) seems to cause the error.

Here is the relevant bzr.log snippet:
