actual Version does not find common element-collection

in the actual debian-version (qelectrotech_0.90.r7473-1_amd64.deb qelectrotech-data_0.90.r7473-1_all.deb) QET does not find the default system-wide element-collection.

The directory where the collection is stored is "/usr/share/qelectrotech/elements",
the setting is "default" but in the tree I only see my user-elements.

In the config-file I find these settings:

[elements-collections]
common-collection-path=default
custom-collection-path=/home/ich/Projekte/qet/elements
custom-tbt-path=/home/ich/Projekte/qet/titleblocks

When I set the directory to "custom" (/usr/share/qelectrotech/elements) all elements are shown...
