Amule crashes almost every time a file is just terminated (ending its downloads).

This is an old error which I've been suffering since Xubuntu 14.04 and with several packages of amule, using official ones, which may or may not be a SVN compilation. In this system, with a freshly install of Xubuntu 18.04 and installed from Universe repositories as version 1:2.3.2-2, behaves just the same as it behaved with a SVN version in 16.04. Not always, and without apparent indication of why, when a download ends (the file is at 100% and it is in the process of rebuilding the file) the error happens. You can continue, but it will appear again and again, until amule crashes and closes. You can check the "do not inform me of this error again" and then it continues and finally crashes. Mostly, you find the computer without amule running and checking the timestamp of its log file and the reported finishing time for the files in it, and the timestamps of the recent downloads, it appears that the error happens just the same as when you can see it (being watching the program): at the end of certain downloads.
