connman-vpn service crashing upon starting with systemd

Hey there,

I'm trying to set up a VPN client with connmand with the help of connman-vpnd.

After having configured a VPN provider for it correctly (as far as I can tell) with the help of man 5 connman-vpn-provider.config, it crashes on 2 of the systems I tried it on.
Both systems are fully up to date and have the openvpn package installed.

When trying to find  the cause of this crash, I used journalctl -xe as root and found this core dump for connman-vpnd:

Process 15139 (connman-vpnd) of user 0 dumped core.
Stack trace of thread 15139:
#0  0x00007fee97e32290 g_str_hash (libglib-2.0.so.0 + 0x35290)

#7  0x000056454ccf350e n/a (connman-vpnd + 0xc50e)

I tried downgrading glib2 to a few versions without any results.

Can anyone point me in the direction on how to fix/log this issue?

Also out of curiosity: how does one go about starting to debug this issue on the relevant programs, connman-vpnd and glib?

To get proper debug traces you will have to recompile the affected programs/libraries with their debug symbols intact, see: https://wiki.archlinux.org/index.php/De … ing_Traces for a general guidance in how to do this.

Re: connman-vpn service crashing upon starting with systemd

Thanks for the pointer V1del.

Is there anyone with a working connman-vpn setup? Hard to find similar issues online, could also be that I'm doing something wrong in the config file.

Still, a segfault is not ideal.
