wxbanker Segmentation Fault on start with appmenu gtk

[Lucas Roesler]

I currently have version 0.8.0~ppa1~10.04 installed on Ubuntu 10.04. Every time I try to start the program I get a segmentation fault.

[Paul Dirksen (pidikun)]

Me too. Same version.

[Michael Rooney (mrooney)]

Thanks for the report! So nothing ever appears? There is bug https://bugs.launchpad.net/wxbanker/+bug/617361 which occurs when clicking on the summary tab, but I assume that is different?

Could either (or both!) of you attach/comment with the output of running 'env' from a terminal? It will hopefully help with debugging to see if it is an environmental issue. Thanks so much, hopefully I can figure out what is happening!

[Lucas Roesler (theaxer)]

I have attahed the output of 'env' as the text file env-lucas.txt

[Lucas Roesler (theaxer)]

Whoops, I do so much stuff in TeX that I didn't name the file correctly, sorry. I promise it is just a text file :)

[Michael Rooney (mrooney)]

Interesting, thanks! Not a locale issue it appears. I see you are perhaps using the global menu option? If so, I wonder if that could be it. Could you let me know how you installed that so I can attempt to reproduce it, and if so, maybe try without that to confirm if that's it.

pidilein, would you happen to be using a global menu bar?

[Ed Coles (edicoles)]

I'm using the global menu bar

[Lucas Roesler (theaxer)]

Good catch. I am using testing version of the new ubuntu appmenu applet. When I removed the applet wxBanker started right up. I installed the applet from the ppa at : https://launchpad.net/~canonical-dx-team/+archive/une

[Michael Rooney (mrooney)]

Awesome, sounds like that is it! I will install the applet and see if I can't fix/workaround it and release 0.8.1 this weekend.

[Tiago Lopes de Azevedo (tiago-azevedo85)]

I've got Global Menu with Lucid and wxbanker is working fine!

[Karel Kolman (kolmis)]

I also failed to simulate the segfault with global menu from ppa http://ppa.launchpad.net/globalmenu-team/ppa/ubuntu

[Michael Rooney (mrooney)]

I suspect from the data it is a difference between Canonical's appmenu-gtk implementation vs the upstream globalmenu project. Karel and Tiago seem to imply upstream globalmenu works, while Lucas appears to be using Canonical's appmenu-gtk. To anyone else seeing or not seeing, can you confirm if it isn't working you are using appmenu-gtk but if it is working you are using globalmenu?

[Michael Rooney (mrooney)]

I'll open up a confirmed AppMenu GTK+ task based on the input here as I can confirm it as well, in hopes they can provide some feedback.

As a workaround I'll look for a way to disable the global menu for wxBanker. I thought I might be able to override UBUNTU_MENUPROXY and/or GTK_MENUPROXY which is defined in Maverick and might fix the problem, but in Lucid it doesn't seem to use env variables and I can't find a way to disable this so that it starts up.

[Michael Rooney (mrooney)]

I confirmed that I can work around it in Maverick with a patch that disables menu redirection menu unsetting the environment variables before doing anything with wxPython, though I'm still not sure if I can fix it for Lucid users of the PPA.

I'll probably release this for 0.8.1 and then see if I can reproduce it with a trivial wxPython app (maybe the demo) and file a wx bug as well and hopefully figure out where the problem is.

[Michael Rooney (mrooney)]

Okay, I filed https://bugs.launchpad.net/wxbanker/+bug/618440 for the work-around env issue in Maverick as that is "fixed".

I'd still love to hear something from the Canonical DX team about if this is expected/known and if there is anything I can do!

[Alexander Skiba (ghostlyrics)]

So basically there's no way to use wxbanker together with appmenu in Lucid?

[Lucas Roesler (theaxer)]

@Alexander -- well just not with the appmenu indicator applet. You can still use it with the global-menu-applet or if you don't mess with the menu bar.

[Alexander Skiba (ghostlyrics)]

The problem here is that since a few days ago my global-menu-applet has an enormous memory leak though I don't remember making any changes. (i.e. goes up to 700mb and is painfully slow)

[David Barth (dbarth)]

I can confirm the crash with wxbanker. Setting UBUNTU_MENUPROXY= lets it start without crashing.

[Cody Russell (bratsche)]

I'm getting a crash whether I run with appmenu-gtk or not.

[Alexander Skiba (ghostlyrics)]

That is because of a package in the canonical-dx-team/une PPA. I don't know which package though. As soon as I ppa-purged the thing everything was working.

[Michael Rooney (mrooney)]

Thanks so much for looking into this Cody/David, it is really appreciated!

[Sebastien Bacher (seb128)]

the fix has been uploaded

[Alexander Skiba (ghostlyrics)]

Does this require a fix in appmenu-gtk too? Since it still segfaults...

[Michael Rooney (mrooney)]

Alexander, I'll see if I can confirm that today in Maverick, that wouldn't be so good.

[Michael Rooney (mrooney)]

Alexander, are you still seeing problems? I upgraded my Maverick install and see no more segfault and the menu is correctly displayed in gnome-panel (wxbanker 0.8). Using 0.8.1 from the PPA, the menu is displayed as normal because of the env workaround. I'll undo this work-around in 0.8.2 since this bug is fixed, and get that uploaded.

[Alexander Skiba (ghostlyrics)]

nope, in Maverick it's working fine. The "still-segfault" was about Lucid, since the UNE PPA is a bit behind. Keep up the good work and thanks for your time.
