[GNC] Crash when saving mysql to xml

[Uli Hansen]

Hallo,

for some years I had my gnucash-data on a mysql database. Now I want to 
move back to xml for different reasons.

When saving to xml, gnc is crashing.

Searching the mailing list was not successful.

Unfotunately I'm not a Linux or  C expert but I tried to collect some 
information


OS: Linux version 4.13.0-39-generic (buildd at lcy01-amd64-024) (gcc 
version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.9)) 
#44~16.04.1-Ubuntu SMP Thu Apr 5 16:43:10 UTC 2018

GNC: from ubuntu packages

     GnuCash 2.6.12
     Dieses Programm wurde aus Version ed11f6d+ am 2016-04-18 erstellt


gnucash.trace:

gnucash --debug --extra

When the program crashes, I ge the following messages:

* 23:57:42  INFO <gnc.io> [gnc_account_dom_tree_create] lot list=(nil)
* 23:57:42  INFO <gnc.io> [gnc_account_dom_tree_create] lot list=(nil)
