Comment (by Øystein Sture):

 I can confirm that this resolves the issue with default initialized frame
 rate (0/1).

 Note that it still may reduce the resolution of the output time base. For
 example if time base is 1/90000 and frame rate is given as 30/1, the
 resolution will be 1/30 afterwards. I've created a workaround by setting
 the frame rate to 30 / (30 * 90000). I'm dealing with video with variable
 frame rate where the actual frame rate may deviate a bit from the average.
