No, no update. This is something out of the scope of KMyMoney. It works for at
least two more installations (and I bet there are more).

I expect an upstream problem (maybe even only on your installation). Looking at
the first frames of the BT we see

#0  0x00007fffef3dbfa0 in __GI___pthread_mutex_lock (mutex=0x20) at
../nptl/pthread_mutex_lock.c:65
#1  0x00007fff604622da in  () at /usr/lib/x86_64-linux-gnu/libmysqlclient.so.20

and the code to that seems straight forward:

int
__pthread_mutex_lock (pthread_mutex_t *mutex)
{
  unsigned int type = PTHREAD_MUTEX_TYPE_ELISION (mutex);

with the assignment of type being the statement on line 65. A pointer of value
0x20 seems a bit odd and is causing the trouble. This pointer is not provided
by KMyMoney, so nothing we can do about.

Did you ever updated any of Qt, libmysql? Sorry, but this is out of reach for
me.

Do we have anyone else running on Kubuntu 18.04.1 with SQL backend?
