356029 - Memory leak detected while opening a file in an external viewer

Status: RESOLVED DUPLICATE of bug 341872

(Firefox :: General, defect)

Description

[Vlad Berditchevskiy]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1) Gecko/20061003 Firefox/2.0
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1) Gecko/20061003 Firefox/2.0

When a file is opened in an external viewer, a memory leak is detected.

Reproducible: Always

Steps to Reproduce:
1. Try to a file, which can't be viewed by Firefox, for example a CHM file.
2. Associate a viewer with this file type, for example /usr/bin/xchm, activate the check box "Do it automatically...". press OK.
3. From now on, whenever you open a file of this type (in this example CHM), the memory leak detector says:
