xfce-session crashes using shortcut exo-open --launch WebBrowser

[Santiago Roland]

I have ubuntu 12.04 and updated to XFCE 4.10 from PPA. Then i decided to downgrade again to 4.8 using ppa-purge. I successfully downgraded to 4.8 but, as a sort of residual bug, every time i hit a shortcut for browser, xfce-session crashes and prompt for login. The shortcut is "exo-open --launch WebBrowser"

Any ideas?

Regards,

You should try to clean you .config/xfce4 and .cache/sessions directories. There are some config changes from 4.8 to 4.10 in a few components, and downgrading isn't a very good idea because of that.

The bug keeps happening even if deleting .config/xfce4 and .cache/sessions

i attach my .xsession-errors

as a workaround i set the shortcut to simply "firefox" and not the exo-open link...
Even after reseting the directories mentioned in post #3, hitting Super+W (the default shortcut to Firefox) the session crashes the same. So, may be is something that got misconfigured after the downgrade.

I understand the danger of downgrading, but it appeared in many posts (some of those blogs, really popular) about doing this upgrade to XFCE 4.10 and at the end they wrote "if you want to go back" install ppa-purge and hit this 2 commands in terminal, that simple.

If this is not that simple, i mean, if after doing this one gets an unstable behavior, that should be pointed out clearly.
I wonder what else may resulted misconfigured.

Is any good to try some apt-get install xubuntu-desktop --reinstall or reconfigure somehow?

Thanks,

When digging more in the problem, i realized that after the downgrade of XFCE 4.10 to 4.8 the system also upgraded other 50MB of packages and after that asked to restart the computer. I did so, and the odd thing i remember is "i will have to install proprietary ATI drivers again". I use hardware 3D acceleration because i use MatLab and 3D plots. And after the downgrade and those updates, and after restarting the machine, ATI drivers were working and i did not have to install them again. but when i started to plot some 3D graphics, matlab hanged. So i realized that not only the "exo-open --launch WebBrowser" was not working, but MatLab was not giving me 3D plots. So i reinatalled ATI Drivers and Matlab worked again, and "exo-open --launch WebBrowser" worked too!! it was a ATI Driver problem.

Tagging solved.
