That happened to me with older versions. The one you mentioned is quite recent... but...
I think you should download the Debian 13 version.
Tips:
If your DAW has multiple paths to lv2 configured, make sure only one plugin version is installed, and that it's not duplicated in multiple locations.
This won't prevent the error you mentioned, but it will prevent potential plugin crashes.
Personally, I prefer to install it locally by hand (by extracting the .deb file and copying drumkv1.lv2 to where I keep my plugins) and not rely on automated installation from repositories. I've experienced situations where distributions decide to change the installation paths. Besides, it's not very useful for a plugin (which should be as portable as possible) to have administrative privileges.
Try downloading the latest version. 1.4.1
