Actually, I got a bit more information. Attaching a debugger and re-running yields this backtrace:
#1 0x00007ffff662d537 in abort () at /lib64/libc.so.6 #2 0x00007ffff69c18dc in () at /usr/lib/gcc/x86_64-pc-linux-gnu/10.1.0/libstdc++.so.6 #3 0x00007ffff69f0966 in () at /usr/lib/gcc/x86_64-pc-linux-gnu/10.1.0/libstdc++.so.6 #4 0x00007ffff69f09d1 in () at /usr/lib/gcc/x86_64-pc-linux-gnu/10.1.0/libstdc++.so.6 #5 0x00007ffff69f0c73 in () at /usr/lib/gcc/x86_64-pc-linux-gnu/10.1.0/libstdc++.so.6 #6 0x00000000004822c8 in SharedFontState::getFont(std::string, int) () #7 0x00000000004c1f14 in SettingsMenu::SettingsMenu(RGSSThreadData&) () #8 0x0000000000478fd2 in EventThread::process(RGSSThreadData&) () #9 0x00000000004610b9 in main ()
I could not get more information out of this. Does it maybe require a certain font to be installed? I tried to install corefonts, but this did not help.
Alternatively, I assume it tries to open a dialog box? Which kind? Do I need to install a special desktop environment (e.g. gnome) for this to work?
