Hi Dimitri,
We are unable to reproduce any crash while dynamically
changing TabStripPlacement when the device is subjected to portrait orientation.
We have attached a sample in which we tried to reproduce the reported
problem.
Please find the sample in below link,

If the problem still persists, please provide us more
information or modify the sample to reproduce the reported problem.
Regards,
Vignesh V
