well, I think we have two issues here: First is that ansari.test is terribly 
picky about certain circumstances. For instance it will fail, if there are 
ties AND and an exact p value is computes AND the confidence interval is 
computed. Pretty impossible to guard against this, I'd say.

The second issue is how to display the error messages. I agree it's not pretty 
right now, but at least the error does get shown (in a dialog). I'd rather 
not change this in the plugin, right now. We will need to work some on error 
handling after 0.4.7, anyway, see my mail "Usage of try() statements" a while 
ago. By now, I think solutions 1b and 2c are the way to go (but still 
interested in your comments), where warnings during execution of a plugin 
command will be redirected to the output, automatically.

So anything we add in the plugin, now, would be just a temporary hack to make 
error display slightly prettier, and would need to be removed later on. 
Hence, I don't think it's something to change for 0.4.7.

Regards
Thomas

P.S.: I moved the "paired" parameter to the variables tab instead of the 
options tab. I feel it's a very basic option, and should be on the first tab.
