`apt-get install scim' (which upgraded no packages other than some
others from the scim source package) was enough to fix the problem.[*1]
In particular, no "basic gtk package" was upgraded between the bug
occurring and not occurring.
[*1]: Though possibly my testing wasn't thorough enough to detect a
problem: see below.
If I downgrade scim back to 1.0.2-3, and upgrade gedit and all of its
direct dependencies to the versions in unstable, then the problem still
persists. If I then re-upgrade scim to 1.4.2-1 then... Oh. gedit comes
up OK, but I can get it to crash with a bit of typing using scim. I can
fix that crash by recompiling aspell from source.
Having found problems with scim and now aspell, I wonder what other
crashes are waiting to be discovered?
The choices I see (all unpleasant) are:
(i) libstdc++6 Conflicts with both scim (<< 1.4.2-1) and
libaspell15 (<< 0.60.4-2) [which doesn't even exist yet]
and hope these are the only two needed packages.
(ii) Do nothing: the crashes will eventually go away
when people get around to upgrading their scim and aspell
packages.
(iii) Force mass recompiles again, e.g. by renaming the libstdc++6
package and bumping the soname.
(iv) Maybe some clever runtime trick to detect the problem and give a
more helpful error message?
Hopefully I've missed something. So far my preferences are (i) and
perhaps (iv).
pjrm.
