Mozilla/mozilla/xpinstall/src/nsInstallFolder.cpp
dougt%netscape.com ff1dd2ab65 Fixing tree blocker. nsInstallFolder did not return an error code when 
it could not initialize itself.  This caused crashes and return values which
were not correct.  I also fixed a huge about of memory leaks for allocation
of strings that were never freed.  r=dveditz, a=leaf.
