This is currently not the case, as can be seen by jumping buttons when scrolling the list. So perhaps the size calculation could depend on the available space minus the size of the preview icon + buttons.

Please give the new patch a try for the button layout.

I tried to reproduce the encoding issue. The osmarender theme is gone from both maps.xml and maps-4.5.xml, so I restored the last version (revision 1309106) from SVN containing the theme to http://nienhueser.de/marble/maps.xml and http://nienhueser.de/marble/maps-4.5.xml and set them as provider in the dialog. I couldn't reproduce the issue however no matter which provider .xml file I used and whether I installed or removed the theme locally. It always displays fine here and is saved correctly to the registry file. There's no forced UTF8 conversion or similar in the code as well. So I'm a bit lost where exactly the problem is.

The patch is based on Bernhard's work in https://github.com/shentok/marble/tree/MapThemeDownloadDialog. I'll commit as a git patch series retaining ownership.

One possibility would be to replace the KDE GHNS dialog with this one as well and move the registry file to the local Marble dir (could be an automated migration even). This would require proper testing of course to avoid regressions in the KDE version.
