The problem is, that executing pdf2htmlEX results in a segmentation fault. Here
is a backtrace:

#0  0x00007ffff7442a9f in NOUI_SavePrefs (not_if_script=<optimized out>) at 
././fontforge/noprefs.c:859
#1  0x00007ffff7441fb3 in NOUI_SetPrefs (name=0x55555559d772 
"DetectDiagonalStems", val1=0x7fffffffe850, val2=0x0) at 
././fontforge/noprefs.c:431
#2  0x000055555558f7de in ffw_init (debug=0) at ./src/util/ffw.c:77
#3  0x000055555557fae2 in 
pdf2htmlEX::HTMLRenderer::HTMLRenderer(pdf2htmlEX::Param const&) 
(this=0x555555809660, param=...) at ./src/HTMLRenderer/general.cc:58
#4  0x000055555556cdc4 in main(int, char**) (argc=<optimized out>, 
argv=<optimized out>) at ./src/pdf2htmlEX.cc:421

So the problem is indeed serious but the segmentation fault seems to happen in
fontforge.
