Hello,

Please give a try to the following workaround, and let us know if it worked.

The errors are due to a missing icon in your current GTK icon theme (as the error messages say). One workaround is trying to install a new theme, we can also try to change the icon theme using the gtkrc-2.0 configuration file.

1) Navigate to /usr/share/icons

2) List the directory content. For me, the content of /usr/share/icons is:

Adawaita, HighContrast, Humanity, Humanity-Dark, LoginIcons, default, hicolor, locolor, ubuntu-mono-dark and ubuntu-mono-light.

3) Create a file in your $HOME with name .gtkrc-2.0 and the following content:

gtk-icon-theme-name="Humanity"

If you don't like the Humanity icon theme, or you don't have it available, you can choose other theme changing "Humanity" for any of the icon themes you have in /usr/share/icons.

4) Save the contents of .gtkrc-2.0 and restart gtkplastic. Change the theme if the error persists.

Regards,

Carlos.

It is only started to work after installation legacy gtk 2 iconset in kde settings. Because it is using legacy icons i am afraid that can happen one day when it will be not possible to use it anymore because old iconset will be removed from distribution.

Beside this, modal window "Icon 'unknown' not present in theme" absolutely block any actions with gui inteface. Not possible even to close application.  Is it possible to change little bit policy about error reports for example all not critical errors send to log files only without modals.

Basically linux gtk client looks little bit outdated. May be exist sense to move to qt instead of gtk ?

May be as a another solution to prevent such kind of issues : will be nice to have opportunity to configure iconset (icon mappings) inside config files.

Or may be i think the best it will be nice to add Plastic own iconset to plastic client installation package and place all needed icons to installation directory . In this case you unbind your project from different linux distributions .
