Same problem for me.
PPC arch

[Kurt Hallavej (kridhvidneger)]

me too

amd64 arch

[der_vegi (m-may)]

me too. amd64, daily build from march 16th.

[Ian Jessen (07imj)]

crashes for me on amd64. 1.5-1ubuntu1 (feisty)

[gremi357 (gremi357)]

me too ... amd64 feisty

[Jonathan Gibert (jokot3)]

the same here, amd64, pretty the same stacktrace

join gdb bt and strace outputs ...

[Jonathan Gibert (jokot3)]

strace output

[Ernst (ernst-blaauw)]

Here too... amd64 feisty

[Cian Davis (davisc)]

Crashes here on AMD64 Feisty, but not on my laptop with 32bit Feisty. 2 straces attached. From AMD64 machine (texmaker.strace) and from laptop (texmaker.strace.working)

[Cian Davis (davisc)]

Apologies. Thought attachments could be added 1 at a time.

[der_vegi (m-may)]

still there on feisty final. the first time i start it, it survives a few seconds. from then on it crashes immediately: i can see the startup logo and for about half a second i see the main window before it crashes.

[Richard Kleeman (kleeman)]

Confirmed here on amd64. Some observations:
It works fine on i386
It crashes in gnome and kde (amd64) but not in enlightenment
It does not crash if run as
gksudo texmaker

[Cian Davis (davisc)]

Confirmed regarding it being OK if you run gksudo texmaker.

I've run strace on this. It outputs 74,254 lines. Files is attached.

Seems to be mainly 2 lines about "Resource not available". Counted these lines with sort texmaker-root.strace | uniq -c | sort -n

Output as follows (only lines counted more than 1,000 times)
   1755 read(16, "10497 (texmaker) S 10496 10497 1"..., 8191) = 249
   3092 read(16, "10497 (texmaker) S 10496 10497 1"..., 8191) = 246

   8649 close(16) = 0
  12495 read(15, 0x7fffb7c2d4e0, 1) = -1 EAGAIN (Resource temporarily unavailable)

Anyone have a clue what this means?

[James Clemence (jvc26)]

+1 here, 32bit Texmaker no issues, 64bit (AMD64 Ubuntu standard texmaker package from the repositories) same exit as above, segmentation fault.

[Bjorn Hansen (holomorph)]

Also segfaulting on me running amd64, but works on my i386 machine.

Here's the strange bit: if I change the $HOME environment variable to point somewhere else it does not crash. For example

bjorn@berserker:/home/bjorn$ export HOME=/home/bjorn/tmp/
bjorn@berserker:/home/bjorn$ texmaker
Qt: Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed
bjorn@berserker:/home/bjorn$ export HOME=/home/bjorn/
bjorn@berserker:/home/bjorn$ texmaker
Segmentation fault (core dumped)
bjorn@berserker:/home/bjorn$

It runs fine, as far as I can tell in the first case, just producing the Autentication Rejected message, but with the standard home directory it crashes.

[Joseph Smidt (jsmidt)]

Can somebody test the new texmaker-1.6 in gutsy to see if this bug persists. Texmaker-1.6 fixes this bug in Debian Unstable.

[Tessa (unit3)]

I just backported this to my Fiesty system, and it does seem to fix this problem. Is it possible to get this into fiesty-backports, since the package in fiesty is broken? Or will this just have to wait until Gutsy?

[Jørgen Kristoffersen (jorgekri)]

Gutsy AMD64, texmaker-1.6.1ubuntu launches without segfault.

[Tessa (unit3)]

I confirm that this appears to be fixed in gutsy.
