[LAU] Aeolus segfaulting

Hey hey,
after a long time, I have started Aeolus again, with the following command:
aeolus -J -S /usr/share/aeolus/stops
After all registers are retuned Aeolus segfaults in the readline initialisation. 
Gdb tells me that the last message comes from libncursesw.so.6 (no specific 
function). Going "up" in gdb I get the following:
#2  0x00007ffff74ae746 in _nc_read_entry2 () from /usr/lib/libncursesw.so.6
#3  0x00007ffff74a73ea in _nc_setup_tinfo () from /usr/lib/libncursesw.so.6
#4  0x00007ffff74a7772 in _nc_setupterm () from /usr/lib/libncursesw.so.6
#5  0x00007ffff74a7cb4 in tgetent_sp () from /usr/lib/libncursesw.so.6
#6  0x00007ffff75089bd in _rl_init_terminal_io () from 
/usr/lib/libreadline.so.8
#7  0x00007ffff74ed51d in rl_initialize () from /usr/lib/libreadline.so.8
#8  0x00007ffff74ed7ed in readline () from /usr/lib/libreadline.so.8
#9  0x00007ffff7fc819e in Reader::thr_main() () from /usr/lib/aeolus_txt.so
...

I am running Aeolus 0.9.7 from the Arch Linux community repo. I have
also tried installing this version manually, with the same result.
Checking with Gdb the correct aeolus_txt.so file is loaded from the
correct aeolus executable, i.e. /usr/local/bin/aeolus for the self-built
version.

I have not encountered any other issues with ncurses or readline based
programs.

Ncurses version: 6.1.6
Readline version: 8.0.0
One system specialty: the terminals are resized using stty, to get an
effective size of 80x30.

Can some one verify this issue with the text UI? Any suggested remedies
perhaps?

Best wishes and thanks,

Jeanette
