inkscape suddenly uses all memory when changing font

[amelieb]

When I change the font (like testing 4-5 fonts one after the other ), Inkscape freezes and starts to use something like 85% of my 4 Go of RAM (I've checked the memory usage with «top»). After a few seconds/minute, it can work again almost as usual but if I try again to change the font it will start again to use 85% of the memory.

Inkscape 0.46
Ubuntu 8.04.1, 64-bit

I've had the same problem with Gimp, so it seemed to be a problem with Gnome's font manager or something like that.

I've try to found which font caused the problem and when I kept the font attached to this comment (OldSlavicRegu.ttf) out of ~/.fonts, everything went fine.

The bug can always be reproduced when the font is in ~/.fonts, then with Inkscape or Gimp going through the font list, when I pass over «OldSlavic Regu» or even just before reaching this font, the software freezes and uses something like 85-95% of the memory.

Hi,
Do you consider this behavior as a problem with the font or a problem with inkscape ?
In the former case we can close the bug repport, otherwise we may have to do something about it.
thanks

Hi nightrow,

I don't know if the problem is a kind of corrupt font, but I think that Inkscape should not in this situation freeze as it does and use 90% of the memory.

previewing the font 'OldSlavicRegu.ttf' in the font selector dropdown list and rendering a text object with this font in Inkscape 0.47 on OS X 10.5.8 does not freeze the ui but gives these these console messages:

I don't get those warnings in the console. Plz re-test.

Arch Linux 64-bit, KDE Plasma 5
Inkscape 0.92pre1 15054 (GTK3)

Not reproduced on Windows XP (32-bit), Inkscape 0.91.
Different issue with lp:inkscape/0.92.x, rev. 15207. Inkscape now crashes when selecting the font in the text toolbar's font selector or in the text dialog (when applying the font change).

Short debug trace (well, yes, on Windows...):
----
(gdb) bt
#0 0x6598b24b in FT_Glyph_Get_CBox () from d:\dev\Inkscape\0.92.x\inkscape\freetype6.dll
#1 0x0071e657 in font_instance::FindFontMetrics() ()
#2 0x00000000 in ?? ()
----

So there's something wrong in the font that Inkscape doesn't handle correctly.
