Today I have exported my kmail configuration with pimdataexporter tool. The progam generated a zip file of the selected configuration but every time
I try to import such configuration file either in the same machine or another one the $ pimdataexporter --import whatever.zip command fails.
It opens a window selection dialog which should shows the configuration entries of the configurations you would like to restore or not, but instead it shows an empty list and you can't restore anything.
I have alredy tried to regenerate the zip file with $ pimdataexporter --export many times and to import the configuration again with the same unsucessful outcome.
