Status: RESOLVED INVALID

(SeaMonkey :: MailNews: Message Display, defect)

User-Agent:       Mozilla/5.0 (OS/2; U; Warp 4.5; en-US; rv:1.9a1) Gecko/20051021 SeaMonkey/1.1a Mnenhy/0.7.2.0

After setting mail.compose.max_recycled_windows to 1 in prefs.js (see Bug #104989 for details and history of this pref), subsequent composition windows open more quickly and MailNews appears to perform well. However, upon entering any text in the View box in the Search Bar (see View | Show/Hide | Search Bar), Mozilla crashes (exits without notice), leaving the following in POPUPLOG.OS2:

MAILNEWS.DLL 0001:0006eb54

Note that the symptom occurs after the second or third time entering text in the View box, not upon the first entry of criteria.

Reproducible: Always

Steps to Reproduce:
1. Close Mozilla.
2. Set mail.compose.max_recycled_windows to 1 in prefs.js; save the file.
3. Start Mozilla MailNews.
4. Enter something in the View box in the Search Bar.
5. Clear the search criteria.
5. Enter something else in the View box in the Search Bar.

Actual Results:  
Mozilla exits abruptly, apparently crashing in MAILNEWS.DLL.

Expected Results:  
Mozilla should not crash.

Bug occurs with default theme (though the first time this happened was with Sky Pilot Classic). Resetting mail.compose.max_recycled_windows to the default value of 0 has resulted in this issue not reappearing, even after entering several different criteria in the View box at various times and over long sessions.

Workaround is to not use mail.compose.max_recycled_windows to increase the performance of redrawing the composition window.

I tried this lots of times and it always worked fine with

Mozilla/5.0 (OS/2; U; Warp 4.5; en-US; rv:1.9a1) Gecko/20051113 SeaMonkey/1.5a Mnenhy/0.7.2.10017
and
Mozilla/5.0 (OS/2; U; Warp 4.5; en-US; rv:1.8) Gecko/20051112 SeaMonkey/1.0b Mnenhy/0.7.2.10017

Maybe your old mnenhy version is the cause, it's known to be problematic on the current trunk.

Thanks, Peter. I've since upgraded Mnenhy to 0.7.2.10015 (per your suggestion on the ng), and I'll give this pref another try now. I'll submit a follow-up report, and close the bug at that time, if things appear stable for a couple days. If the problem appears again, I'll ask Karsten for the 0.7.2.10017 nightly you are using (or uninstall Mnenhy) and test again.

This does indeed appear to have been a XUL cache issue. I can no longer reproduce. Marking as Resolved/Invalid.
