What size has is a "big php file" ? :]

[Malix (malix0)]

The file size is 81626 byte. And contain a class with several method and properties. Quanta crash after some edit. Some time it crashes immediately after cut and past.
To reproduce the crash try to open a big file and write same new row of code. If it doesn't crash try insert a if block of code. To me looks that the code parser doesn't free memory. But I could be wrong.

I download kdewebdev-dbg. How I can use it to produce a more detailed backtrace?

Bye Massimo.

[P (p92)]

fixed in http://bugs.kde.org/show_bug.cgi?id=120983

[Malix (malix0)]

Now the bug is closed. But when the patched package will be posted on archive?

[Daniel Holbach (dholbach)]

One task is enough.

[Loïc Corbasson (cnb)]

As it is fixed in 3.5.2, you'll have to add the following lines in your /etc/apt/sources.list (with your editor of choice):

deb http://kubuntu.org/packages/kde352 dapper main
deb-src http://kubuntu.org/packages/kde352 dapper main

AFAIK the 3.5.2 packages will be included in Dapper only if they are proven to provide more bug fixes than new bugs, so helping test these packages can only increase their chance to make it into Dapper. Nevertheless, I'm not a Kubuntu developer, so I may be wrong about the inclusion of 3.5.2 in Dapper.

[Luka Renko (lure)]

KDE 3.5.2 packages are already included in Dapper. The above repository is not required (it is obsolete).

Just do the following:

sudo apt-get update
sudo apt-get upgrade

[Raphaël Pinson (raphink)]

Closing the bug as it was fixed in Dapper.
