Rinex 3 obs file reading error

[GeoDev80]

I am using GPSTk python bindings for my work, I get the following error while reading RINEX 3 Hourly observation data files
-------------
InvalidRequest: text 0:G03 index 11 is not available.
location 0:/home//GPSTk-2.10/core/lib/FileHandling/RINEX3/Rinex3ObsData.cpp:234
--------------

I can see that the obs data field in RINEX3 obs file is empty for SV#G03, the software crashes when I run it during obs file reading stage.
Is there any updated Rinex3ObsData.cpp which can handle the missing data gaps.
Has any one faced a similar problem, and have a solution.
Any suggestions to handle this, please share them, would be very helpful.

Cheers!
