If SmartSVN does not start any more on some Linux systems, e.g. Manjaro, the file ~/.config/smartsvn/14.2/logs/log.txt.0 might indicate a problem loading libcrypt.so.1. This could be related to a recent update of the glibc bundle where /usr/lib/libcrypt.so.1 had been removed. To fix this, please find out which bundle contains this file now:
$ pacman -F libcrypt.so.1
On Manjaro one has to install the libxcrypt-compat bundle.
