Unhandled exception: TypeError: stat() argument 1 must be (encoded string without NULL bytes), not str

Binary package hint: apport

I have entries like the following in /var/log/apport.log:

apport (pid 9923) Wed Apr 9 03:27:48 2008: called for pid 12999, signal 11
apport (pid 9923) Wed Apr 9 03:27:48 2008: Unhandled exception:
Traceback (most recent call last):

  File "/usr/lib/python2.5/posixpath.py", line 171, in exists
    st = os.stat(path)
TypeError: stat() argument 1 must be (encoded string without NULL bytes), not str

This is with Ubuntu Hardy, apport 0.107

Thanks. Since apport catches exceptions, it is just a cosmetical problem. If we cannot read the executable path from /proc, then we lose anyway, and the best we can do is to gracefully ignore it.

I'm wondering if this is the correct way to do it.

This release of Ubuntu is no longer receiving maintenance updates. If this is still an issue on a maintained version of Ubuntu please let us know.
