It was simple enough to create a new profile from scratch for the affected user. Now thunderbird works. So, something was broken in that user's profile.
If that can be two cents to encourage Mozilla to make a "reset profile" feature like they did for Firefox, that would probably make things up.

Status in thunderbird package in Ubuntu: New Bug description: # Context On a Ubuntu 12.04 machine used by several users (two main users), Thunderbird has been used for years on various WiFi networks. Each user has his Unix account, one thunderbird profile, using IMAP server. Users don't connect to same e-mail provider. Yesterday evening, we moved to a usual alternate location with its own wifi. # Observed behavior Now one user has thunderbird crashing whenever it searches for folders, and that happens at startup, before user has a change to click anywhere. Thundebird only shows a window, in status bar a message like "looking for folders" with a progress bar at about 10-15%, then crashes. The user can access their mailbox normally via a webmail supplied by the IMAP provider. Folder names look normal there. Other user is totally unaffected by the problem. Reproducible: always. Expected behavior it obvious: no crash, user can browse their folders. # Additional information * Safe mode does not change anything, whatever the boxes checked (addons, toolbars). * Cutting off internet access allows to start thunderbird without immediate crash. * Changing these settings to false (they were true) is not enough to prevent crashes on startup with network access. user_pref("mail.server.server1.login_at_startup", false); user_pref("mail.startup.enabledMailCheckOnce", false); * In preference, unticking "sync messages for this account" does not prevent crash on startup. # Debug information Thunderbird crash reporter worked. I clicked yes when offered and typed a short sentence. This way I have submitted 21 crash reports today. Following https://wiki.ubuntu.com/MozillaTeam/Bugs I got stack traces that I can attach. package is 1:31.3.0+build1-0ubuntu0.12.04.1 I don't know if source matches http://dxr.mozilla.org/comm- central/source/mailnews/base/util/nsMsgUtils.cpp, but from the top of the stack tracs it looks like MsgHashIfNecessary() was supplied with an empty string, which may be the cause of crash. #0 NS_MsgHashIfNecessary (name=...) at /build/buildd/thunderbird-31.3.0+build1/mailnews/base/util/nsMsgUtils.cpp:446 lastIndex = -1 illegalCharacterIndex = <optimized out> hashedname = "\000`\271\377\377\377\177\000" keptLength = <optimized out> Crash ID: bp-0744c6e8-13b6-4ff1-85ea-083022141223 Crash ID: bp-0f5ff99f-ae29-4300-b14c-5d3ec2141223 Crash ID: bp-1bc04187-d16c-428c-b226-02fa42141223 Crash ID: bp-1f928c7d-822b-43ad-9893-96c4f2141223 Crash ID: bp-2cb3dc60-f364-4836-82a1-1a86f2141223 Crash ID: bp-2e400b3c-aeac-48ec-8f18-33fbe2141223 Crash ID: bp-33c39df8-2565-4af4-bc57-d2ced2141223 Crash ID: bp-3e9b7666-1a2f-409e-beff-996e62141223 Crash ID: bp-68e88235-dc96-4b01-a803-9808f2141223 Crash ID: bp-71e10918-f8c5-41a6-a41f-91eca2141223 Crash ID: bp-9ee0e84a-217a-417e-b78c-501d82141223 Crash ID: bp-a173490f-5d76-4303-9e74-e72812141223 Crash ID: bp-b4f12af0-eb61-43d2-9939-ac11a2141223 Crash ID: bp-b5e9cf00-7da8-4dda-b172-964082141223 Crash ID: bp-b96e3d2c-dbaf-473e-b628-ba4f12141223 Crash ID: bp-bb1815ce-bd07-4809-9971-614ee2141223 Crash ID: bp-c42a1d6c-102e-4eee-abc6-08f0d2141223 Crash ID: bp-c9aa9ffc-183e-437d-b534-1a9c12141223 Crash ID: bp-d916ad64-68ae-4823-8d38-4f3912141223 Crash ID: bp-dc99e352-05ba-4819-95bc-0bd502141223 Crash ID: bp-e2d83623-5d39-4480-add2-ea8d72141223 lsb_release -rd Description: Ubuntu 12.04.5 LTS Release: 12.04 LC_ALL=C apt-cache policy thunderbird thunderbird: Installed: 1:31.3.0+build1-0ubuntu0.12.04.1 Candidate: 1:31.3.0+build1-0ubuntu0.12.04.1 Version table: *** 1:31.3.0+build1-0ubuntu0.12.04.1 0 500 http://fr.archive.ubuntu.com/ubuntu/ precise-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu/ precise-security/main amd64 Packages 100 /var/lib/dpkg/status 11.0.1+build1-0ubuntu2 0 500 http://fr.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: thunderbird 1:31.3.0+build1-0ubuntu0.12.04.1 ProcVersionSignature: Ubuntu 3.2.0-74.109-generic 3.2.64 Uname: Linux 3.2.0-74-generic x86_64 NonfreeKernelModules: nvidia AddonCompatCheckDisabled: False AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
