Bug#323705: libgtk2.0-0 should use more recent libcairo (libcairo2)

[Jan C. Nordholz]

Package: libgtk2.0-0
Version: 2.7.2-1
Severity: normal
Tags: experimental

Hi,

(please adjust severity, I'm unsure what to set it to)

the experimental libgtk2.0 is using a pretty old version of libcairo,
which it seems has even been removed from the archive (it's not part
of any current release or pseudo-release). This alone doesn't pose a problem,
but please note the current dependencies between libgtk, libpango and
libcairo:

libgtk2.0-0 DEPENDS ON: libcairo0.5.1 (>= 0.5.1), libpango1.0-0 (>= 1.9.0)
libpango1.0-0 DEPENDS ON: libcairo0.5.1 (>= 0.5.1)

libgtk2.0-dev DEPENDS ON: libcairo0.5.1-dev, libpango1.0-dev (>= 1.9.0)
libpango1.0-dev DEPENDS ON: libcairo0.5.1-dev

Now that libpango (== 1.10.0-1) has migrated to the new libcairo2, libgtk
is pulling in both cairo libraries, which makes every gtk-/pango-based app
segfault. Here's one of the SEGVs (reason pretty obvious ;-) ):

(gdb) bt
#0  0xb76ad08b in cairo_scaled_font_destroy () from /usr/lib/libcairo-1debian0.5.1.so
#1  0xb756bfa3 in cairo_font_options_get_hint_metrics () from /usr/lib/libcairo.so.2
#2  0xb756d9f2 in cairo_font_options_get_hint_metrics () from /usr/lib/libcairo.so.2
#3  0xb75679ff in cairo_set_font_options () from /usr/lib/libcairo.so.2
#4  0xb7750d57 in pango_cairo_layout_path () from /usr/lib/libpangocairo-1.0.so.0

Please upgrade libgtk to use libcairo2.



Best regards,

Jan
