Interesting. If you are still able to reproduce the crash, can you try to get the line number within virSecurityManagerGenLabel where the crash happened? I think it's the STREQ line (440 linenr). Question is whether model or name is NULL.
src/security/security_manager.c-438- for (i = 0; i < vm->nseclabels; i++) {
src/security/security_manager.c-439- for (j = 0; sec_managers[j]; j++)
src/security/security_manager.c-440- if (STREQ(vm->seclabels[i]->model, sec_managers[j]->drv->name))
src/security/security_manager.c-441- break;
src/security/security_manager.c-442-
src/security/security_manager.c-443- if (!sec_managers[j]) {
src/security/security_manager.c-444- virReportError(VIR_ERR_CONFIG_UNSUPPORTED,
src/security/security_manager.c-445- _("Unable to find security driver for label %s"),
src/security/security_manager.c-446- vm->seclabels[i]->model);
src/security/security_manager.c-447- goto cleanup;
src/security/security_manager.c-448- }
src/security/security_manager.c-449- }
