I got this error too when installing it with FAM. The shortcut appeared but did not launch Mieru. Running "apt-get install -f mieru" in X-Term solved the problem.

This apps sounds very cool, cbrPager anc Comix were missing a few features (like volume buttons to change pages, great idea) and this one is much more minimalistic, but very efficient. I think it will become my prefered one.

I second the idea of a "preload next page" function to improve navigation.

Thanks!
