Ubuntu 9.10, clean installation from scratch (not an upgrade) and Revelation 0.4.11 from official repos.
"Open file on startup" does not work if directory holding a password file have 'space' in the name.
The application finds the file, ask you for password and after entering the password the error message appears:
<Traceback (most recent call last):
File "/usr/bin/revelation", line 261, in <lambda>
self.datafile.connect("changed", lambda w,f: self.state_file(f))
File "/usr/bin/revelation", line 478, in state_file
os.chdir(os.path.dirname(file))
OSError: [Errno 2] Nema takve datoteke ili direktorija: '/home/sinisap/Ubuntu%20One/Revelation'>
The program does not crash here, just ignores the password file which can be normally opened with File - Open.
When renaming Ubuntu One to UbuntuOne I have no problems. Interesting enough, the Revelation manages to find a file and ask for a password. It just cannot open it after the password is entered.
