Description hackitforfun 2017-04-25 11:14:44 UTC

Using the 17.04 version cantor.

Way to reproduce:

1. In arch linux, install cantor, sagemath, maxima, r.
2. Start cantor, choose any one of the sage, maxima, or r sessions.
3. Initializing takes forever.
4. When clicking cancel while initializing, the corresponding help menus
(Show Sage Help, Show Maxima Help, Show R help) appear normally and usable. The session, however, is blank, without cursor etc.

Thanks for your report hackitforfun. I am putting it as Invalid because you submit several problems as one bug. I recommend to you submit each problem as a different bug.

Some comments about the problems:
1. Sage - I need to know the version of Sage you utilized here.
2. Maxima - Maxima works fine, so I need to know the version too.
3. R - R is broken since some releases, see Bug 351871.
