Tue Apr 20 22:35:19 UTC 2010

Pdfsam is broken with gij also here, and the errors are not consistent.

(a minuscule window gets shown; if I make it larger dragging the
corners, I can see the menu bar and the tool bar, but without any
command in the main window. I don't think it is usable; the splash
window was displayed without problems)

Another run:

(the window is just as before)

Still another:

(this time nothing is show, pdfsam crashes miserably).

I really thing that pdfsam cannot go with gij. Maybe the wrapper script
could be written so that it prefers openjdk or sun Java, instead of the
default one in the system, like we do with josm (which has the same
problem).

Cheers, Giovanni.
