My librsvg2 is current - 2.56.0 :-(.
Found "-k czq 500" is okay, but "-k czq 400" fails 5 times on out of memory,
and leaks in cairo_recording_surface_create from FT_Glyph_To_Bitmap, according
to valgrind. "-k czq 380" is just not runnable (and valgrind warns of "set
address range perms: large range" too). The out of memory happens between 477
and 478.
I am wondering also that because the arabic font means negative advance widths
for most glyphs, and due to an over-sight, any glyphs other than the first few
get those negative advance widths passed to cairo as widths :-( , so the rsvg
port code is doing some insanely large numbers from wrap around, for small
negative bitmaps....
I have an Adobe latin svg font which works perfectly fine under ftview. (Though
it has only a dozen glyphs, and nothing more exciting than "ABCDE...")

Hin-Tak,
SVG rendering is handled by librsvg. If that buffer does not have correct
dimensions set, you might have all kinds of crashes. Therefore, try updating
that library. You might have a faulty version.
