MATLAB: Is the MATLAB path cleared when I try to add a directory using the PATHTOOL or ADDPATH functions in MATLAB 7.0 (R14)

addpathblankdirectoryMATLABpathtool

When I use the PATHTOOL function to add a path to my directory, the path listing becomes blank and MATLAB can no longer find any functions. This also happens when I try to use the ADDPATH function to add a directory. For example, the following commands:
addpath('c:\')
path
result in the following error:
 ??? The path may be bad.  Please save your work (if desired), and quit.
When using PATHTOOL, the directory listing goes blank.

This bug has been fixed for Release 14 SP1 (R14SP1). For previous releases, please read below for any possible workarounds:
This has been verified as a bug in MATLAB 7.0 (R14) in the way that MATLAB handles an environmental variable called ICU_DATA on the system PATH.
