Thanks.

> I hope apitrace was invoked right ...

Yep, it reproduces the issue fine:

  $ glretrace konqueror.trace
  src/gallium/auxiliary/gallivm/lp_bld_tgsi_soa.c:1887:lp_emit_declaration_soa:
Assertion `idx < 256' failed.
  apitrace: warning: caught signal 5
  1585: error: caught an unhandled exception
  apitrace: info: taking default action for signal 5
  Trace/breakpoint trap


One can see the expected output by doing (on a non-crashing driver like
NVIDIA):

  $ glretrace -S 1585/draw konqueror.trace
  Wrote 0000001585.png
  Rendered 0 frames in 0.269629 secs, average of 0 fps

Here are the source shaders:
