Looks like a similar case to the bug #1000210: tvtime wants to read from user's home directory and expects the HOME environment variable to be set.

An workaround for this bug and bug #1000210:

In files src/tvtime-command.c
         src/tvtime-configure.c
         src/tvtime-scanner.c
         src/tvtime.c

add this lines after int main( int argc, char **argv ):

 int main( int argc, char **argv )
 {
+ if( !getenv( "HOME" ) ) {
+ fprintf( stderr, _("tvtime requires environment variable HOME to be set.\n") );
