Rtorrent Caught Segmentation fault after update ubuntu 19.10 to 20.04 #987

I updated my system, understand until 20.04. which is too early on the first day of release, but what has been done is done .. When starting, rtorrent crashes into Caught Segmentation fault Empirically, I found out that if you comment out session.save = yes then rtorrent works. What could be the reason?

rtorrent

Hello, see issue #928, it is about session.save.

I got everything working through the rtinst script on my Ubuntu 20.04, but suddenly rtorrent won't start and I get this in the logs (either the auto start or by just running rtorrent command): Caught Segmentation fault, dumping stack: rtorrent(+0x40b1b) [0x55ccecd62b1b] /lib/x86_64-linux-gnu/libpthread.so.0(+0x153c0) [0x7fa910f503c0] /lib/x86_64-linux-gnu/libc.so.6(+0xbed8a) [0x7fa910c0bd8a] /usr/lib/x86_64-linux-gnu/libxmlrpc.so.3(+0xd30a) [0x7fa910f7630a] /usr/lib/x86_64-linux-gnu/libxmlrpc_xmlparse.so.3(+0x5ab1) [0x7fa9105fbab1] /usr/lib/x86_64-linux-gnu/libxmlrpc_xmlparse.so.3(+0x7bd6) [0x7fa9105fdbd6] /usr/lib/x86_64-linux-gnu/libxmlrpc_xmlparse.so.3(+0x8db2) [0x7fa9105fedb2] /usr/lib/x86_64-linux-gnu/libxmlrpc_xmlparse.so.3(+0x967b) [0x7fa9105ff67b] /usr/lib/x86_64-linux-gnu/libxmlrpc_xmlparse.so.3(+0xa1d0) [0x7fa9106001d0] /usr/lib/x86_64-linux-gnu/libxmlrpc_xmlparse.so.3(xmlrpc_XML_Parse+0x136) [0x7fa9105fd436] /usr/lib/x86_64-linux-gnu/libxmlrpc.so.3(xml_parse+0xd3) [0x7fa910f76563] /usr/lib/x86_64-linux-gnu/libxmlrpc.so.3(xmlrpc_parse_call+0xb0) [0x7fa910f76a60] /usr/lib/x86_64-linux-gnu/libxmlrpc_server.so.3(xmlrpc_registry_process_call2+0xc5) [0x7fa910f839f5] /usr/lib/x86_64-linux-gnu/libxmlrpc_server.so.3(xmlrpc_registry_process_call+0x29) [0x7fa910f83b89] rtorrent(+0x18147c) [0x55ccecea347c] rtorrent(+0x17ff47) [0x55ccecea1f47] rtorrent(+0x1809c7) [0x55ccecea29c7] /usr/lib/x86_64-linux-gnu/libtorrent.so.21(_ZN7torrent9PollEPoll7performEv+0xca) [0x7fa910feae4a] /usr/lib/x86_64-linux-gnu/libtorrent.so.21(_ZN7torrent9PollEPoll7do_pollEli+0x69) [0x7fa910feaf59] /usr/lib/x86_64-linux-gnu/libtorrent.so.21(_ZN7torrent11thread_base10eventloopEPS0+0x12b) [0x7fa911020f6b] Aborted (core dumped)

Hello jariivanoff, I think this is another issue. Your stack output shows that something is wrong with XML RPC code. It might be related with configuration options deprecation and rewriting but I don't use XML RPC so can't test this. I would suggest to open new issue but change the topic to more specific one (mention XML RPC).
