You should use spacing instead of count for your photons.
That way, you set the density of the photons coverage and don't spread 
your photons between the various objects and light_source.
Also, if one object seems to receive enough photons, but the other 
don't, you can use target float.
The float value is to be used as a multiplicator for the spacing.
target 0.5 will reduce the effective spacing for that object by half, 
for 4 times as many photons.

If you want the photons to be reflected by the mirror, using target 2 or 
3 will reduce the number of photons dirrected at the mirror. As it's a 
flat surface, it don't need as much coverage as the glasses.

It is impossible.
One vase without glasses also incorrectly draws caustic.
I attach a scene.
You can adjust?
For me it will be a good example during the work on the exporter.
Thanks in advance!

Yes. Problem.

The following photon block in global_settings{} works well for the 
glasses. If you remember, we did a Blender scene test last year and this 
comes from my version then:

   photons {
     spacing 0.01  // higher value 'lower' quality, faster parsing.
     gather 20, 100
     autostop 0
     jitter 0.5
     max_trace_level 15
     adc_bailout 1/10e5
   }

See attached image.

However, for the vase, something funny happens and parsing seems to be 
stuck in a loop, eating up memory.

I think the mesh2{} of the vase is corrupt. This is how it shows up when 
loaded in Poseray.

That is a mess. Have you tried deleting orphans and recalculating the 
normals?

To be more explicit: I guess that the mesh2 was made from an object 
where the face normals were not all consistent, some facing inwards, 
some outwards. This is typical for objects made with some high-end 
modellers (!) or exported with a low resolution. So, what I would 
suggest to Lanuhum is to check the original vase object.

I thought that you might have. :-)

That's what it looks like to me too.

I did this vase for testing of Yafaray.
Yafaray has problems with heavy scenes, but
no problem with vase mesh.
If there is a problem in a mesh, probably it is the exporter's problem.

That is a possibility indeed. Could you provide an .obj version of the 
vase? Maybe I can see where the problem resides.
