Choosing a filter in gmic window results in displaying its config, but also spawning error window with text like this:

Sorry! G'Mic failed, reason:*** Error in ./gimp_bokeh_preview/gimp_split_preview/ *** Command '-repeat': Invalid argument '@#'.

Sorry! G'Mic failed, reason:*** Error in ./gimp_blur_angular_preview/gimp_blur_angular/ac/_apply_channels/*if/*if/ *** Item substitution '{-arg 1+7,all,rgba,rgb,rgb_r,rg(...)l,cmyk_c,cmyk_m,cmyk_y,cmyk_k}': Unrecognized item 'arg 1' in expression '-arg 1...'.

(most filters give message with '-repeat' but there are variations)

The message reappears each time after changing filter settings. Trying to apply filter causes similar error window to appear (and no filter is applied).

Reproducible: Always

Steps to Reproduce:
1. Filter -> G'MIC
2. Choose filter

Actual Results:  
Error message


This problem is most likely connected with recent gmic update in ae72033ae50e9d4f56030e9ee5d5ee5ae759fea2 (i've done bisect to make sure).

I also tried to "Update definitions", but it doesn't seem to do anything except for making cursor busy.
