#28 adding source folder fails when in clearcase

[Max Waterman]

Developing in a clearcase view, everything seems to
work fine apart from the 'Source' tab. It says there is
no source available for the functions. When I try to
add a source folder (Settings/Configure
KCacheGrind/Annotations/Add...), it says that 'The file
or directory [cwd] does not exist.' where [cwd] is the
directory from which I launched kcachegrind.
