I don't want to discourage anyone from contributing to the community, but I wonder if adding
gksu to the repository is really required. To me at least it would be also a bit contrary to the spirit of TC, which I consider to be in favour of avoiding "bloatware".
We might not need gksu to correct the PCMANFM behavior: According to the README file of pcmanfm (v0.5.2):
Switch To Root Problems:
In "Tool" menu of PCManFM there is an option for you to switch to super user.
By default PCManFM calls 'gksudo', and if it doesn't exists, it calls 'gksu'.
If both of them don't exist, PCManFM will call 'kdesu'.
In some distros, 'gksudo' is disabled by default. Instead, you can assign your
preferable program during configuration, and the option is
"--with-preferable-sudo=PROG"
So, I'd imagine rebuilding PCMANFM with "
--with-preferable-sudo=sudo" might resolve the problem, without having to go through depencency hell to create some "GUI bloat".
