--- Comment #6 from Bernhard Übelacker bernhardu@mailbox.org --- Sorry, this should read: After installing the distributions "samba" package the crash is no longer visible.
With a debug information enabled build the crash is here: #0 in RtlCompareString@12 at wine/dlls/ntdll/rtlstr.c:392 #1 in LsaLookupAuthenticationPackage@12 at wine/dlls/secur32/lsa.c:1014 #2 in ?? () from c:/softethervpn/vpnsmgr/vpnsmgr.exe ...

A simple check of loaded_packages[i].name being not null before feeding it into RtlCompareString would also avoid the crash.
