Comment # 9 on bug 1162419 from Michael Andres

@Ancor: Checking the YAST logs with:

> grep 'y2base called with\|Launched YaST2 component\|sigsegvHandler\|--root'

you find that this is the last successful install by sw_single qt:

Subsequent invocations of sw_single qt now crash reliably and are not able to
install any packages. The above updated libyui-qt11 but no packages of the zypp
stack. In fact the last upadte of the zypp stack happened 2019-12-29
(libzypp-17.20.0, zypper-1.14.33) as visible in the zypp/history file.

Checking the history file you also find that after the libyui-qt11 update
zypper commands still operate flawlessly and are able to install:

> 2020-02-01 14:27:45|command|root@localhost|'zypper' 'up' 'yast2-packager'|
> 2020-02-01 14:44:39|command|root@localhost|'zypper' 'install' 'code'|
> 2020-02-01 14:46:36|command|root@localhost|'zypper' 'install' 'scrot'|
> 2020-02-01 14:48:52|command|root@localhost|'zypper' 'install' 'sqlite3'|
> 2020-02-03 17:34:37|command|root@localhost|'zypper' 'update' 'libzypp' 'zypper' 'yast2-pkg-bindings' 'yast2' 'yast2-packager'|

I'm still not convinced that this is a libzypp issue.



@macias:
Could you please try if using yast2 ncurses shows the same behavior as the qt
backend?
