OOPS, sorry. The bug is win32-only, I mis-applied Jorgen's patch for network
shares when I refactored it. Thanks for reporting this. I've just updated
svn and released an rc2 with the fix. If you want to apply it manually, it's
trivial:
Index: IPython/genutils.py
===================================================================
--- IPython/genutils.py (revision 979)
+++ IPython/genutils.py (working copy)

finally:
os.chdir(path)
else:
- shell_ori('"pushd %s&&"'%path+cmd,verbose,debug,header)
+ shell_ori(cmd,verbose,debug,header)
shell.__doc__ = shell_ori.__doc__
Thanks for the report.
Cheers,
f
