The current version of x11-misc/zim in portage is almost a year old. I tried renaming the ebuild to the latest version (x11-misc/zim-0.52) and it seemed to work fine. I tested it on amd64 and I think I used all the plugins added since 0.47 (first time trying out the software, so was trying out lots of features). Encountered no problems. Reproducible: Always
