In rpmqv.c ther is the code

    fprintf(fp, _("%s (" RPM_NAME ") %s\n"), __progname, rpmEVR);

Unfortunately, xgettext (apparently) doesn't expand RPM_NAME.  Only
the string "%s (" gets into the message catalogue.

A possible solution would be

    fprintf(fp, _("%s (%s) %s\n"), __progname, RPM_NAME, rpmEVR);

It would not translate the name.  But names are usually not
translated.

On the other hand, given that the string now contains no text, there
isn't much to translate.  So an even simplier solution would be

    fprintf(fp, "%s (" RPM_NAME ") %s\n", __progname, rpmEVR);
