Solution: File a bug on b.g.o. Maybe the acroread dev can bundle a libidn.so.11 with acroread. Workaround: Symlink libidn.so.11 on some location outside the usual lib directory structure (I suggest /usr/local/acroread/lib). Create a shell script wrapper around acroread which calls `LD_LIBRARY_PATH=/usr/local/acroread/lib acroread` That way, only acroread will "see" this lib. Hope this helps, Florian Philipp
