Just crashed again, minutes later (it was working for hours before!). However, I get a different memory error this time...

[Vincenzo Ciancia (vincenzo-ml)]

I think this bug would be better placed in the upstream bug reporting system; if someone does this, please link the bug here.

[tchu11 (tchu11)]

A similar problem also affects me, and it is now occurring frequently. I have filed a bug report on LyX bug tracker as well, see:

http://www.lyx.org/trac/ticket/6052

Their reply is they have attempted fixing it, and upgrading to version 1.6.3 should solve the problem. Can the version on Ubuntu repository be upgraded to this version as soon as possible please?

We will need to try the latest version to see if the bug persists.

[No (11111nonononono-deactivatedaccount-deactivatedaccount-deactivatedaccount)]

Could you try LyX in Ubuntu Karmic and see if it works there?

[arno_b (arno.b)]

When it crashes, is your cursor not visible ? It may come from a bug, fixed in 1.9.3, that happens when you type while the cursor is not visible.

[Rob Oakes (robertsoakes)]

This appears to be related to LyX Trac Bug #6680, and occurs due to an incompatibility with LyX 1.6.5 (currently available from the Lucid package repositories) and Qt 4.6. This issue has been repaired in LyX 1.6.6 and greater. For Meercat, Ubuntu should consider syncing the LyX package with the Debian testing. See Launchpad bug #618690.

[Jean-Marc Lasgouttes (jmarc)]

This should work now, LyX 1.6.6 is old history.
