Well, proj doesn't like the parameters:
proj +proj=omerc +lat_0=46.952405556 +lonc=7.439583333 +alpha=90.000000000 +k=1.000000000 +x_0=2600000.000 +y_0=1200000.000 +ellps=bessel units=m
Rel. 4.4.5, 9 January 2002
<proj>: 
projection initialization failure
cause: lat_0 = 0 or 90 or alpha = 90
program abnormally terminated

That Thuban doesn't give you a better error message is obviously a bug
in Thuban. I filed a new bug report for it:
