hugin dumps core every time when quiting

[nobody]

Hugin (laest svn, not a new feature) does not quit cleanly, but dumps a core, It prints backtrace and mamory map.

The core is not saved under default settings in my computer. I am running Ubuntu Linux 7.10 + daily updates.

This seems to be the relevant part:

I have now noticed that core dumping only occurs if the preview window is open when quiting. The whole text dump (DUMP1 belo) complains about /var/cache/fontconfig. I cleared the cache and got a very informative report (have a look at DUMP2). However after that time, the error messages point to ~/.fontconfig/ (DUMP3). Clearing that directory allows hugin to exit once without error messages. That fills up ~/.fontconfig/ again and hugin dumps core in all consecutive runs unless it is cleaned.

The filling /var/cache/fontconfig might have been done by an older version of hugin or some library it uses since that directory is not used any more.

I might have made mistake of not giving the whole output previously, so here comes:

I can confirm this on SVN2955 running on WinXP

Hugin crashes every time the main application window is closed when there is a preview window still open.
Start Hugin, open an existing project (alternatively, start a new project and add some images to it), open preview window.
Go back to main Hugin application window and attempt to close it -- Hugin crashes.

isn't this a duplicate of <https://sourceforge.net/tracker/index.php?func=detail&aid=1934989&group_id=77506&atid=550441> ?

[Lukas Jirkovsky (l-jirkovsky)]

Is it still valid? I can't reproduce it here on Linux. In my opinion it looks like some problem with wxwidgets (at least in linux), because hugin AFAIK doesn't use fontconfig directly.

[tmodes (tmodes)]

Very old. Maybe not valid any more. Setting status to incomplete
